1.	Give plausibleexplanation for each of the following:(i) Cyclohexanone forms cyanohydrin in good yield but 2, 2, 6trimethylcyclohexanone does not.(ii) There are two −NH2 groups insemicarbazide. However, only one is involved in the formation ofsemicarbazones.(iii) During the preparation of esters from a carboxylic acidand an alcohol in the presence of an acid catalyst, the water or theester should be removed as soon as it is formed.
