Which of the following will be most stable diazonium salt `RN_(2)^(+)Xbar` ? .

Options

A. `CH_(3)N_(2)""^(+) X^(-)`
B. `C_(6)H_(5)N_(2)""^(+)X^(-)`
C. `CH_(3)CH_(2)N_(2)""^(+)X^(-)`
D. `C_(6)H_(5)CH_(2)N_(2)""^(+)X^(-)`

Answer

B

Explanation

`C_(6)H_(5)N_(2)""^(+)X^(-)` is most stable diazonium salt because of resonance stabilization.
