🚀12th Chemistry || 🎯Most IMP Topic || HSC Board ||🥇 Chapter 9 to 16 #class12thboard @a2zpractical991

Hello, kids. How are you all? I think you'll be very happy in your lives. And this time, your exam preparations will go very well. So I won't waste your time with all these things. I am going to tell you some important topics from the key chapters here. What do you do then? You kids get tired of watching videos. Means videos like this on YouTube. Their lives are going on, their videos, their lives are going on, their videos. We're doing all this here. But we don't know what is actually important or what questions to ask. So today I am going to discuss all the important questions here. Just keep a book in往事 front of me, like your Maharashtra handbook, Maharashtra's test book. Keep a pencil with you. So that whatever questions I ask you, you will quickly check them. In two days, you'll have to study all of this. And nothing more than this. And you will get it easily. In 70, you will easily get 65 marks. Whatever I am going to tell you here, just do it. Alright, let's begin. Take out your handbook and take a pencil. Whatever questions I will tell you here, you have to tick all of them quickly. And the same questions will take you two days. That means you have to prepare the same questions within two days. So to get ready with me. Come on, if you're going to open the test book without it, then don't sit in front of me. Okay, open the test book. Come on, I'll start my session here. And today we will discuss all the important questions from 9 to 16. All the important questions. Which you have to cross out, circle, put anything on, and get ready. Alright, that's all you need to study. You don't have to do anything else here. And understand everyone, child. And child, one of the big mistakes you are making. You are sitting through people's YouTube sessions for 5 to 4 hours. And you don't understand anything there. I'll say, whatever is important, check it. And read it yourself. Child, you will get good marks. You will sit here and there. You will also realize that your time is running out. Time is being ruined. You don't understand anything there. You just reply to people's comments. You see, yes, it ends. It ends at this point. Don't do this, child. Please don't do this. And watch my strategy video. And in the previous videos, I covered all the chapters. Like 1, 2, 3, 4. See that as well. Alright, let's do it quickly. I won't take much time. Because I know that this is a crucial time for children. Okay, I'm not going to take that time from you. Child, I'll just discuss some important matters here and then leave. Alright, because right now you need to focus on studying yourself. Not that you have to rely on others. Okay, let's go. See, in the ninth chapter, I initiate the bond of coordination. And child, see what you must learn here. Okay, first you should know what is meant by ligands. It will be somewhere around here. See the ligands. See, ligands are directly linked to the central metal ion through coordinate bonds. What are ligands called? Okay, now list 2-3 types of ligands. Okay, like a polydentate ligand. And in the polydentate ligand, EDTA, a hexadentate ligand. Like EDTA, ethylenediaminetetraacetic acid. Do it and leave. The example of EDTA is frequently requested. What is EDTA? Which example is it? It is often asked. Are my videos stuck? One minute, one minute, one minute, one minute, one minute. Let me see. The video should not be stuck. I think it's stuck. Okay, but just wait 2 minutes. Let me check once. Are my videos stuck? Alright, alright, let's go. All children, like the videos first. Then I am going to give you these things. Okay. Just 2 minutes, child. Let's go. I think the videos are not stuck. Okay, let's go. Look here. Ethylenediaminetetraacetic acid This is the full form of EDTA. Examples of hexadentate ligands are requested. Do it. Okay, let's move on. You also know the definitions of ambidentate ligands. Okay, so see. Mark the ambidentate ligand. See what to mark? Mark a ligand. What is an EDTA ligand? It comes to define. Examples of hexadentate ligands include EDTA and related chelating agents. And after that. What is an ambidentate ligand? It comes as well. After that child. Oxidation state I mean. Anyone will give you. They will be like FECN 6. And they will say what is the oxidation state of whom. Find out. According to this formula. You will know. Find out. Do it. Will you do it? Alright, let's go. Next is ours. Coordination number Now look at the coordination numbers. You should come as well. Okay. Like look here. Look. This is like. Coordination numbers. You should know. Like. Look how many people are injured. The same coordination number. Tells. Okay, like here. This is an ambidentate ligand. So here. Coordination number 3 2 6 will be done. Okay, this is also. Ambidentate ligand So 3 2 6. This coordination number. I am explaining for MCQ. I'm clicking too. Double salt and coordination compound. This is a very important question. What is meant by double? Its definition. And its definition. More. Do not go beyond this. After that. Postulates of Warner Do not leave assumptions. Are you doing Tik-Ma or not? If you're doing Tik-Ma with me. Don't tell the children. You will do it. Just sitting here and there, nothing happened on YouTube. Work hard, study at night, study in the morning, do all of it Don't do anything else; just check on YouTube, it'll be a waste of your time. Waste time, watch on YouTube, your time will be wasted Waste your time, read at night, read in the morning, waste time at night, watch on YouTube—your time will be wasted. Watch on YouTube; your time will be wasted. The favorite chapter for everyone is halogen derivatives. halogen derivatives The most important chapter for everyone Nothing can be done from here. There's nothing to do here. Nothing at all Come here directly Look here Now, here, the importance of reactions is not there. You must perform these three reactions. If you want to produce chlorine from alcohol, what would you need to do? To produce bromine from alcohol, what needs to be done? If you want to make iodine from alcohol, what needs to be done? These three reactions Known through PCl3, PCl5 Delete it The one I'm talking about is thionyl chloride. Go like this. Go forward after that After that, see what needs to be done halogen exchange And You have to do these Swartz reactions, kid. You have to do it no matter what. Don't miss it Don't miss it, or you'll miss a lot more. This is not everything. clearance what is the definition What you need to do next This is it. optical activity Writing in black color Just do it. Inençyors Defined as Doing it here not with me Children, you people are doing this, not that. The truth is, don't just sit idle on YouTube. Use this time wisely. It's waste and dust everywhere... OK Got it, important done after that Definition of racemic mixtures means definition of enantiomers Definition of chiral carbon: A carbon atom bonded to four different atoms or groups. Definition of optical activity: The ability of a substance to rotate the plane of polarized light. Definition of racemic mixture: A racemic mixture is a 1:1 mixture of two enantiomers of a chiral molecule, resulting in no net optical activity because the rotations caused by each enantiomer cancel each other out. Do it, but don't leave it like this either. And all this, you must leave everything behind, after that, the child will come here and drink this yellow one. Every time there was a board exam, a question came from this yellow one. What do they ask? How will you prepare alcohol from halite? How will you prepare ether from halite? How will you prepare cyanide from halite? How will you prepare nitro from halite? Among these are the ones that come, the ones that are mistaken, the ones that go after doing. I'll finish this chapter and then take everyone's comments. Take the yellow one, then the child Sun-1 Sun-2 must be Write now, wherever you are writing, write Sun-1, Sun-2—I must go after doing this. Alright, this was your Sun-1 and Sun-2. Alright, let's move forward from here, from Fatkh. And here it is, ours Alright, here are our Wittig reactions and Grignard reactions. Just do both. The war reactions are taking a toll. Barry J. Verge and the fitting reaction and fitting reaction Three Know both alkylation and acylation And if the judges have to do it, then you Just go ahead and use the DDT Just go ahead and use DDT And who should I appoint as judge, huh? And Feon Gas Just use Tencher Iodine and Feon Gas DDT, Feon, and Tencher Iodine If you need to use these, go ahead and use them. He has already said so. Come on, smash it, smash it, take your damn ducks Say it, say it—whatever importance you're emphasizing, the child must do exactly that much. Alright What doubt do you have, sir? This child is definitely genuine. Because in physics everything was given, but nothing exists. Sir, please tell me, is it not like that in chemistry? No, kid, I haven't learned this yet. If you're a new viewer, please like the video and subscribe to the channel—it really motivates us a lot. Please like the video and subscribe to the channel; it really motivates the creator a lot. How is Teflon made? How is polyacrylonitrile made? Polyacrylonitrile, also known as acrylic, is nylon, so I've told you. Just take a look at the structure of Bakelite. Dekaron and Bakelite sa Bakelite novella and Decarion Very important, indeed, different What happens in the industry, this is used Okay, write about Buena Vista. Alright, let's go, I think that's enough Okay, now we'll move forward Peej B.B., Peej B.B. Polymers Just remember this one Pij B.B. Alright, now comes Pij B.B. Polymers Alright, let's go, hurry up Do just this much, do it. Alright, in the last chapter, you'll find the importance. I'm about to tell you, just take a look at him, he's the best one. Last chapter, nothing but vote green chemistry Look, if you happen to have it, just take it. Just do it. After that You don't have to do all this. Do only as much as I tell you, okay? Tell me about green chemistry. after the definitions Just do it. Nano science Just do it. And what happens in nano, up to 100 nanometers? We study anything for the sake of the vaccine. After that Define nanotechnology It is defining everything. Defining one by one, line by line. I am speaking to you. Come on Next Applications Go through the entire application carefully. Applications of Nanomaterials After that, it will remain included in this. This disadvantage I'm telling you the truth. Please specify If you remain that much exhausted He hasn't gone anywhere. 65 to 70 marks Nothing will come from outside. What is one? To grow big, eat plenty of vegetables You'll get good marks in no time. You won't get anything by running away here. Alright, let's see what I do with sessions and what I do.
