Periodic Acid Oxidation

Find the structure of (X).

I posted this question earlier also and got the reply as which I think is correct. But I would like to know if the answer to the above question can also be the one given below (besides the above answer):-

Is this answer also correct? If your answer is NO , then please give the reason.

Find the structure of (X).

I posted this question earlier also and got the reply as which I think is absolutely correct. Madhusudan Sir gave the answer. But I would like to know if the answer to the above question can also be (besides the above answer):-

If not, then please tell the reason.

EXPERTS PLEASE REPLY.

Hi Debotosh!

Is the answer to your question the one given below:-

If not correct, yaar please correct me and give the correct answer. I really want to know.

Thanks!

Yaar, koi baat nahin. You were trying to help me out. You didn't have the intention of posting wrong answer. You gave it a try atleast.

Can the correct answer also be the compound given below? If not, please give the reason also.

Give the product formed on heating 1,1,2-cyclohexanetricarboxylic acid with acetic anhydride.

Please answer.

Your answer is correct. Can this also be the correct answer?

Sir, can the compound (X) be the one given below also? Please answer.

Thanks a lot sir for correcting the mistake, because I had accepted the answer given by the previous child.

Sir, you are really doing a great job by helping students like this.

Find the structure of (X).

Which has greater migratory aptitude? Hydride ion OR Phenyl group? Please explain.

Heating acetone with sulphuric acid leads to the formation of mesitylene (1,3,5-trimethylbenzene). Propose a mechanism for this reaction.

I think it has to be similar to acid catalyzed aldol condensation reaction. Please think from the that perspective also.

All your replies are cordially invited.

I also had this solution with me. But I was not able to understand the statement regarding the phase difference in part(a). This is because I was taking the origin of the motion at the extreme end. But now I have got it.

Thanks a lot!

Please give solution of Q no 41 (all the parts) Pg-255 Chapter:- SHM HC VERMA Part-I

No need reply to this question. I have got the answer to this question.

Thanks a lot, if any of you had tried it.

-OH group does not have +I effect rather it has an -I effect due to the strong electronegative oxygen atom.

I know the mechanism.

I also think that the ortho product should be the major product but I'm not able to find a concrete proof for it.

If you (or someone else can also answer) can provide a proper explanation for it, then please do so. Your replies are cordially invited.

Please answer.

Since in the tautomerisation, the para isomer is in conjugation, so the transfer of proton should not be affected with the position.

That is both para and ortho are in conjugation, so the distance should not be an issue here. What do you say?

I'm having a question which is like:-

Which of the following statement(s) is/are correct when an alkaline solution of phenol is refluxed with chloroform at 60 degree celsius?

(a) Dichloro carbene is formed as an intermediate.

(b) Ortho isomer is the major product.

(c) Intramolecular proton transfer takes place.

(d) Intramolecular hydride transfer takes place.

The answer given is (a),(c)

According to you, then the answer should be (a),(b) and (c). Please explain the deviation.

Please answer

What is chloropicrin? Please give the structure.

Grignard reagents are synthesized when RX reacts with Mg in the presence of ether. Ether in this reaction serves to stabilize the Grignard reagent by co-ordinating with through its basic oxygen atom. Which of the following ether would be best to stabilize the Grignard reagent?

(a) tetrahydrofuran

(b) diethyl ether

(c) ethyl isopropyl ether

(d) diisopropyl ether

Please give the explanation also, describing why the answer given by you is more stabilizing than the rest of the options (i.e. if your answer is (a), then why is it more stabilizing than (b)).

When an alkaline solution of phenol is refluxed with the chloroform at 60 degree celsius, which is the major product? Is it an ortho isomer or para isomer?

Please give explanation for the product formed (i.e. which one is major and why)?

Someone please answer!!!!

Can someone explain why only (a) and (b) are correct? Since all of them are bases and the racemix mixture is an acid, so all the four given options should react (as they are bases) with the acid. Can someone explain?

OR is the answer given in the book incorrect?

Please reply.

Find the structure of (X).

Find the structure of (X).

Give the product formed on heating 1,1,2-cyclohexanetricarboxylic acid with acetic anhydride.

Find the structure of (X).
