(a) Give a plausible expianation for each one of the following : - (i) There are two - `NH_(2)` groupsin semicarbazide. However, only one such group is involvedin the formation of semicarbazones. (ii) Cyclohexanone forms cyanohydrin in good yield but `2,4,6`-trimethylcyclohexanone does not. (b) An organic compound with molecular formula`C_(9)H_(10)O` forms, `2,4`- DNP derivative, reduces Tollens\' reagent and undergoes Cannizzaro reaction. On vigorous oxidation it gives 1,2-benzene-di-carboxylic acid. Identify the compound.
