Giving plausible explanation for each of the following:
i. Cyclohexanone forms cyanohydrin good yield but 2,2,6-trimethylcyclohexanone does not.
ii. There are two `(-NH_(2))` groups in semicarbazide. However, only one is involved in the formation of semicarbazones.
iii. During the preparation of esters from a carboxylic acid and an alcohol in the ester should be removed as soon as it is formed.

Give plausible explanation for each of the following: (i) Cyclohexanone forms cyanohydrin in good yield but 2,2,6-trimethylcyclohexanone does not. (ii) There are two -NH_(2) groups in semicarbazide. However, only one is involved in the formation of semicarbazones. (iii) During the preparation of esters from a carboxylic acid and an alcohol in the presence of an acid catalyst, the water or the ester should be removed as soon as it is formed.

Give explanation of following : (i) During the preparation of esters from a carboxylic acid and an alcohol in the easter should be removed as soon as it is formed.

During the preparation of esters from carboxylic acid andalcohol In thepresence of acid catalyst, the water or the ester should be removed as soon as it is formed. Give reason.
