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.

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 alkyl compound (C_5H_(11)X) is an optically active compound. The compound was treated with metallic magnesium in ether and the product on treatment with ethanol produces 2-methyl-butane. Write all the reactions and find out the structure of the alkyl halide

What happens when carbonyl compound is treated with zinc-amalgam and concentrated hydrochloric acid? Give chemical equation. What is name of the reaction?

An organic compound has the molecular formula C_5H_(10)O . The compound does not reduce Tollen's reagent but reacts with Brady's re-agent to give orange precipitate. On vigorous Oxidation, the molecule produces ethanoic acid and propanoic acid. The com-pound also gives iodoform test. Identify the compound and write equations for chemical reactions involved.

What happens when an acidic solution of the green compound 'B' is allowed to stand for sometime. Give the equation involved. What is the type of reaction called.

An organic compound 'A' having molecular formula C_6H_6O gives a characteristic colour with aqeuous FeCI_3 solution. When 'A' is treated with CO_2 and NaOH at 400K under pressure 'B' is obtained.
