An aliphatic compound 'A' with molecular formula C₂H₃Cl on treatment with AgCN hives two isomeric compounds of unequal amounts with the molecular formula C₃H₃N. The minor of nthese two products on complete reduction with H₂ in the presence of Ni gives a compound 'B' with  molecular formula C₃H₉N. Identify the compounds 'A' , 'B' and write the reactions involved.

Carry out following conversions:
(a) Toluene to m-bromotoluene
(b) Benzene to m-bromoaniline

Give the structures of A, B and C in the following reaction: 
(a) \({ C }_{ 6 }{ H }_{ 5 }{ NO }_{ 2 }\overset { Fe/HCI }{ \longrightarrow } A\overset { { HNO }_{ 2 };273K }{ \longrightarrow } B\overset { { C }_{ 6 }{ H }_{ 5 }{ OH } }{ \longrightarrow } C\)
(b) \({ C }_{ 6 }{ H }_{ 5 }{ N }_{ 2 }CI\overset { CuCN }{ \longrightarrow } A\overset { { H }_{ 2 }O/{ H }^{ + } }{ \longrightarrow } B\overset { { NH }_{ 3 };\triangle }{ \longrightarrow } C\)

A colourless substance 'A' (C₆H₇N) is sparingly soluble in water and gives a water soluble compound 'B' on treating with mineral acid. On reacting with CHCl₃ and alcoholic potash 'A' produces an obnoxious smell due to the formation of compoung 'C'. Reaction of 'A' with benzenesulphonyl chloride gives compound 'D' which is soluble in alkali. With NaNO₂ and HCl, 'A' forms compound 'E' which reacts with phenol in alkaline medium to give an orange dye 'F' . Identify compounds 'A' to 'F'.

Why is an amide more acidic than amine?
