Reactions of `C_(6)H_(5)CH_(2)Br` with aqueous sodium hydroxide follows……..

Options

A. `S_N^1` mechanism
B. `S_N^2` mechanism
C. Any of the above two depending upon the temperature of reaction
D. Saytzeff rule

Answer

A

Explanation

`S_N^1` mechanism depends upon the stability of carbocation. Higher the stability of carbocation, higher will be the possibility of `S_N^1` mechanism to take place. In the given compound, `C_6H_5CH_2Br` carbocation is `C_6H_5overset(oplus)CH_2`. This carbocation `C_6H_5overset(oplus)CH_2` is a stable carbocation due to resonance, therefore, its show `S_N^1` mechanism.
