1.	(a) Write the structures of A and B in the following reactions : (i) C_(6)H_(5)N_(2)^(+)Cl^(-)overset(CuCN)to A overset(H_(2)O//H^(+))to B (ii) CH_(3)COOH overset(NH_(3))underset(Delta)to A overset(NaOBr)to B (b) Write the chemical reaction of methyl amine with benzoyl chloride and write the IUPAC name of the product obtained. (c) Arrange the following in the increasing order of their pK_(b) values : C_(6)H_(5)NH_(2),NH_(3),C_(2)H_(5)NH_(2),(C_(2)H_(5))_(2)NH
Answer» SOLUTION :(a) (i) `A=C_(6)H_(5)CN` PHENYL cyanide B = `C_(6)H_(5)COOH` Benzoic acid (II) `A=CH_(3)CONH_(2)` Acetamide `B=CH_(3)NH_(2)` Methyl amine (b) `CH_(3)NH_(2)+C_(6)H_(5)COCl to underset("N-Methylbenzamide")(CH_(3)NHCOC_(6)H_(5))` (c) `(C_(2)H_(5))_(2)NH lt C_(2)H_(5)NH_(2)lt NH_(3) lt C_(6)H_(5)NH_(2)`
