Amines

An organic compound (P) on treatment with aqueous ammonia under hot condition forms compound (Q) which on heating with Br2 and KOH forms compound (R) having molecular formula C6H7N. Names of P, Q and R respectively are.

1. Toluic acid, methylbenzamide, 2-methylaniline
2. Benzoic acid, benzamide, aniline
3. Benzoic acid, 4-methylbenzamide, 4-methylaniline
4. Phenylethanoic acid, phenylethanamide, benzamine

A hydrocarbon 'P' (C4H8) on reaction with HCl gives an optically active compound 'Q' (C4H9Cl) which on reaction with one mole of ammonia gives compound 'R' ( C4H11N). 'R' on diazotization followed by hydrolysis gives 'S'. Identify P, Q, R and S.
