Q. An organic compound with molecular formula $C_9{H}_{10}O$ forms 2, 4-DNP derivative, reduces Tollen's reagent and undergoes Cannizaro reaction. On vigorous oxidation it gives a dicarboxylic acid which is used in the preparation of terylene. Identify the organic compound.

Q. (a) Give a possible explanation for each one of the following:
(i) There are two $-N{H}_2$, groups in semicarbazide. However, only one such group is involved in 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's reaction. On vigorous oxidation it gives 1, 2-benzene-di-carboxylic acid. Identify the compound?

Q. An organic compound (A) with molecular formula $C_8{H}_{8}O$ forms an orange-red precipitate with $2,4-\text{DNP}$ reagent and gives yellow precipitate on heating with iodine in the presence of sodium hydroxide. It neither reduces Tollens' or Fehling's reagent, nor does it decolourise bromine water or Baeyer's reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid (B) having molecular formula $C_7{H}_6{O}_2$. Identify the compounds (A) and (B) and explain the reactions involved.
