Which on of the following is more readily hydrolysed by `S_N1` mechanism?

Options

A. `(C_6H_5)C(CH_3)Br`
B. `C_6H_5CH_2Br`
C. `C_6H_5CH(CH_3)Br`
D. `(C_6H_5)_2CHBr`

Answer

A

Explanation

order of reactivity of halides under going`S_N1` reaction is{Benzyl>allyl>tertiary>secondary>primary}
`:.(C_6H_5)_2` `C(CH_3)` Br, being a tertiary halide is more readily hydrolysed by `S_NI` mechanism.
