1.	Which of the following haloakane undergoes nucleophilic substitution reaction by `SN^(2)` mechanism onlyA. `CH_(3)Br`B. `CH_(3)CHBrCH_(3)`C. `C_(2)H_(5)CHBrCH_(3)`D. `(CH_(3))_(3)CBr`
Answer» Correct Answer - A In `SN^(2)` reaction, the reactivity of haloakane occurs in the order `CH_(3) gt 1^(@) gt 2^(@) gt 3^(@)`. The determining factor is steric hindrance in the caron atom of alkyl group attached to halogen atom. There is minimum steric hindrace offerex by teh hydrogenes to the approach of nucleophilie attacking at the carobon of C-Br bond.
