Solution :(a) `C_(6)H_(5)NH_(2) OVERSET(HNO_(2))UNDERSET(HCl)RARR C_(6)H_(5)N_(2)Cl overset(H_(3)PO_(2))rarr C_(6)H_(6)`
(b) `C_(6)H_(5)NO_(2) overset(Sn//HCl)rarr C_(6)H_(5)NH_(2) overset (HNO_(2))rarr C_(6)H_(5)N_(2)Cl overset(H_(2)OO)rarr C_(6)H_(5)OH`
(c ) `C_(6)H_(5)NH_(2) overset(HNO_(2))underset(HCl)rarr C_(6)H_(5)N_(2)Cl overset(KI)rarr C_(6)H_(5)I`
(d) `C_(6)H_(5)NH_(2) overset(HNO_(2))underset(HCl)rarr C_(6)H_(5)N_(2)Cl overset(NaNO_(2))rarr C_(6)H_(5)NO_(2)`
