An organic compound contains A(C_7H_5N) on hydrolysis with strong aqueous acid gives another compound B which is a monobasic aromatic carboxylic acid. The compound B on treatment with ammonia gives a salt which on heating gives C. The compound C undergoes Hofmann's bromamide reaction to yield aniline. Name A, B and C and write the chemical reactions involved.

An organic compound A (C_3H_6O) is resistant to oxidation but forms compound B (C_3H_8O) on reduction. 'B' reacts with HBr to form the compound 'C'. C with Mg forms Grignard reagent 'D' which reacts with 'A' to forms a product which on hydrolysis gives. E. Identify A to E

An optically active amide (A)C_5H_(11)NO on acid hydrolysis gives an acid and NH_3 . When (A) is treated with bromide and alkali a compound is obtained which one treatment with nitrous acid gives an optically active alcohol and nitrogen. The alcohol gives positive iodoform test. What is the structure of A and show the reactions involved.

Two moles of organic compound 'A' on teratment with a strong base give two compounds 'B' and 'C'. Compound 'B' on dehydrogenation with Cu gives 'A' while acidification of 'C' yield carboxylic acid 'D' with molecular formula of CH_2O_2 . Identify the compounds A, B, C and D. Write all chemical reactions involved.
