Which compound in each of the following pairs will react faster in S_(N)2 reaction with OH ion ? (i) CH_(3) Br or CH_(3) I (ii) (CH_(3))_(3) C Cl or CH_(3) Cl |

Answer» Solution :SINCE 1 ion a better leaving group than Br ion , therefore `CH_(3) I` will react faster than `CH_3 Br` in `S_(N) 2` reaction with `OH^(-)` ion . (ii) On steric grounds `I^(@)` alkyl halides are more reactive than tert alkyl halide in `S_(N) 2` reactions . Therefore , `CH_(3) CL` will react at a faster RATE than `(CH_(3) )_(3) C Cl` in a `S_(N) 2` reaction with OH ion . |
