[00:10:50]Because it is a question of 10 marks. A big question will be asked.

[00:10:54]Now look son, let us quickly look at these questions once.

[00:10:59]Ok? Now see what could be the very important questions from unit number second.

[00:11:05]First we have son Pirol. First very important question. Why are pyrrole, furane and thiophene called highly aromatic compounds? Why are pyrrole, furane and thiophene called highly aromatic compounds?

[00:11:20]Also keep in mind son, they may also ask you their IUPEC name. You may also be asked for their IUPEC name. So I have already written all the instructions. You should pay attention to this thing, son. So why are they called highly aromatic compounds? You have to write any two methods of making pyrrole, purine and thiophene. The first one may ask is why are pyrrole furane and thiophene called highly aromatic compounds? And write two methods each for preparing pyrrol furane and thiophene. What more could Next ask for in this one? Discuss the electrophilic and nucleophilic substitution reactions of pyridine. Both can ask and single can also ask. So you should read both of these. Electrophilic and nucleophilic substitution reactions of pyridine. That's right, son.

[00:12:01][nasal sound] Next, look son, I have written some reactions in this or that. So since this reaction is simple, a simple product will be formed in it. Ok? Like look, this is your first reaction. Ok?

[00:12:14]In this first reaction, beta CHCl3 is taking place with chloroform. And who is with you? KOH, so you read about it, what kind of reaction is this, son? Reimer team reaction occurs. I have written answers to a few.

[00:19:24]So look at this, I have been given four questions.

[00:19:26]Number five because these are small. You can ask yourself number five. This is a question of 20 marks. This means you should have minimum three pages in it. Two to three pages. Ok? You should have three pages.

[00:19:39]See what all the son can ask himself from the next unit number second. First write the mechanism of electrophilic substitution reaction of indole pinoline and isoquinoline. Claisen condensation is a small reaction. Ketoenol is a small, five-line formula. I have four lines.

[00:20:00]Comparison of the alkaline properties of pyridine, piperidine and pyrrole. Ok? Which of these is more alkaline and which is less alkaline.

[00:20:05]Next question number 21, look son.

[00:20:08]First, discuss the amplitude series and solvation structure of glucose.

[00:20:13]Son, this is an example of monosaccharide. Take care. So if you ask for an example of monosaccharide, you have to write this. Ok? Don't be confused. Sir, you had told me about glucose, this is monosaccharide.

[00:20:23]What do you understand by next disaccharide? Draw and write the structures of sucrose and maltose.

[00:20:28]Ok? Two parts son because it is a question of 20 marks.

[00:20:32]This question can be asked in 10-10 marks. So that's why it's okay? So no one should panic because a question of 20 marks will be asked. No question of 20 marks will ask you to write the structure of amaltose or sucrose. No, even such a small question will not be asked to you within 20 marks. Next de Broglie is very important. You have to explain the Bohr model of atomic structure based on de Broglie.

[00:20:51]Ok?

[00:20:57]You have to explain the Bohr model of atomic structure based on de Broglie.

[00:20:59]Next, you have that son, a numerical relation to a bullet, calculate the de Broglie wavelength. A spherical relation de Broglie wavelength what do you have to do with yourself son? Have to calculate.

[00:21:12]How much support have you given to him? 0.04 kg and is moving with a velocity of 1 km/s.

[00:21:20]And son, I have a small question about the operator. Whom we call operator.

[00:21:25]Write a note on operator.

[00:21:28]You have told me about the Compton Effect, which is going to be very important.

[00:21:30]Ok? So friends, these were the questions. Now let us discuss it once in English medium also.

[00:21:35]Also for English medium students. First was my son MCO bond I have to tell myself. Ok? In metal carbonyls. Next we have symmetrical hydrogenation. Next, which one was with me, son?

[00:22:26]Ketoenol was irritating. Ketoenol tomerism.

[00:22:30]Next we had to compare the basicity properties of piperine and pyrrole. Ok? These were the questions I had. What was question number 21, son?

[00:22:46]Discuss the open chain and cyclic structure of glucose. What was the next question for question number 21? What do you understand by What do you understand by Dacrides? Write the structure of sucrose and maltose and explain the difference between them. Ok?

[00:23:01]This was question number 21 with us.

[00:23:05]Next look at question number 22. Look son, I had question number 22. Explanation of Bohr's model of atomic structure based on de Broglie's theory.

[00:23:14]That is, explain Bohr model of atomic structure based on de Broglie.

[00:23:19]Wave. Ok? Next, what did you have, son? One of them had numerical.

[00:23:24]Calculate the deBroglie wavelength and find yourself inside it. Associated with a bullet of zero mass 0.04 kg moving with a velocity 1 km/h per second. One had to calculate the de Broglie wave function associated with a bullet. With which it is moving at a mass of 0.04 kg and a velocity of 1 km/s second. Is it okay son?

[00:23:46]What was the last question you had? I had to tell the operator which we call son, operator is not catalyst operator, okay son, I had to tell the operator inside this, okay, I hope you have understood the questions that I have told you, now sir, the question comes about where to get the answers, so whoever has the solid paper, whoever has the solid paper, son, he can see it from there, okay, now by chance suppose someone does not have the solid paper or there is no source to see the answers.

[00:24:18]We have this solution for that. You will find a link to my Instagram ID below. This is not the one mentioned inside it.

[00:24:24]Secondly, you will get the link of Instagram ID.

[00:24:28]Ok? What do you want to do? You have to go to that ID.

[00:24:31]Ok?
