`C_(6)H_(5)NH_(2)overset(NaNO_(2)//HCl)rarrXoverset(Cu_(2)(CN)_(2))rarrYoverset(H_(2)O//H^(+))rarrZ` Z is identified as

A

`C_(6)H_(5)- NH- CH_(3)`

B

`C_(6)H_(5)- COOH`

C

`C_(6)H_(5)- CH_(2)- NH_(2)`

D

`C_(6)H_(5)- CH_(2)- COOH`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(6)H_(5)NH_(2) overset(NaNO_(2)//HCl)rarr underset((X))(C_(6)H_(5)N_(2)Cl) overset(Cu_(2)(CN)_(2))rarr underset((Y))(C_(6)H_(5)CN) overset(H_(2)O//H^(+))rarr underset("Benzoic acid(Z)")(C_(6)H_(5)- COOH)`
Thus product Z is identified as `C_(6)H_(5)- COOH`
