Expain the SN^2 mechanism |
|
Answer» Solution :When METHYL bromide UNDERGOES hydrolysis with aqueous potassium hydroxide, methyl alcohol is formed `CH_3-Br+KOHtoCH_3-OH+KBr` This mechanism INVOLVES only one step  The nucleophile `OH^-` attack from the rear side of the leaving group. A transitlon stale with partial formation of C-OH BOND and partial breaking of C-Br bond takes place simultaneously. The-rate of the reaction depends both on the concentration of nucleophilc as weil as alkyl halide. Hence, it is a second order reaction. In `SN^2` reaction, complete inversion of configuration takes place. |
