Answer»

SOLUTION :
(II) `underset("Methylamine")(CH_(3)NH_(2))overset(HNO_(2))(to)CH_(3)OH overset(PCl_(5))(to)CH_(3)Cl overset(KCN)(to) underset("Methyl cyanide.)(CH_(3)C-=N`
(iii) `underset("Propanenitrile")(CH_(3)CH_(2)C-=N)+H_(2)O underset(H_(2)O_(2))overset(OH^(-))(to) underset("Propanamide")(CH_(3)CH_(2)-overset(O)overset(||)(C)-NH_(2))underset(KOH) overset(Br_(2))(to) underset("ETHANAMINE")(CH_(3)CH_(2)NH_(2))`
