Answer the following questions
The compound of `A(C_(3)H_(9)N)` reacts with benzene sulphonyl chloride to give a solid insoluble in alkali. Identify 'A'

A colourless substance 'A' (C_(6)H_(7)N) is sparingly soluble in water and gives a water soluble compound 'B' on treating with mineral acid. On reacting with CHCl_(3) and alcoholic potash 'A' produces an obnoxious smell due to the formation of compound 'C'. Reaction of 'A' with benzenesulphonyl chloride gives compound 'D' which is soluble in alkali with NaNO_(2) and HCI 'A' forms compound 'E' which reacts with phenol in alkaline medium to given an orange dye 'F'. Identify compounds 'A' to 'F'.

The compound (CH_3)_2CH-CHCl-CH_3 reacts with alcoholic KOH to give the following alkene:

(i) How will you convert phenol to benzoic acid? (ii) An organic compound A having molecular formula, C_6H_6O gives a characteristic colour with aqueous FeCl_3 solution. A on treatment with CO_2 and NaOH at 400 K under pressure gives B which on acidification gives a compound C. The compound C reacts with acetyl chloride to give D which is a popular pain killer. Deduce the structure of A, B, C and D.
