Predict the order of reactivity of the following compounds in `S _(N)1` and `S_(N)2` reactions:
(i) The four isomeric bromobutanes
(ii) `C_(6)H_(5)CH_(2)Br, C_(6)H_(5)CH(C_(6)H_(5))Br, C_(6)H_(5)CH(CH_(3))Br, C_(6)H_(5)C(CH_(3))(C_(6)H_(5))Br`

Text Solution

Verified by Experts

(i) `CH_3CH_2CH_2CH_2Br gt (CH_3)_2 CHCH_2Br lt CH_3CH_2CH(BR)CH_3lt (CH_3)CBr --S_N1 CH_3CH_2CH_2Br gt (CH_3)_2CHCH_2Br gt CH_3CH_2CH(Br)CH_3gt (CH_3)_3CBR--S_N2`
Of the two primary bromides , the carbonation intermediate derived from `(CH_3)_2 CHCH_2Br` is more stable than derived drom `CH_3CH_2CH_2CH_2Br` because of greater electron donating inductive effect of `(CH_3)_2` CH - group .
