Question

`X overset(Sn//HCl) to overset(NaNO_(2))underset(HCl)to Z overset(CuCN)underset(Delta)to (P) overset(H_(3)O)to Ph-COOH` correct options is/are:
A. X is `Ph-NH_(2)`
B. Y is `Ph-NO_(2)`
C. Z is `Ph-NH_(2)`
D. P is `Ph-CN`

Answer 1

Correct Answer - D
`Ph-NO_(2)overset(SN//HCl)rarr PH-NH_(2)underset(HCl)overset(NaNO_(2))rarr PhN_(2)^(+)Cl^(-) underset(Delta)overset(CuCN)rarr Ph-CN overset(H_(3)O)rarr Ph-COOH`
