Question

In S N 2 reactions, the correct order of reactivity for the following compounds : CH 3 Cl, CH 3 CH 2 Cl, (CH 3 ) 2 CHCl and (CH 3 ) 3 CCl is :, CH 3 Cl > (CH 3 ) 2 CHCl > CH 3 CH 2 Cl > (CH 3 ) 3 CCl, CH 3 Cl > CH 3 CH 2 Cl > (CH 3 ) 2 CHCl > (CH 3 ) 3 CCl, CH 3 CH 2 Cl > CH 3 Cl > (CH 3 ) 2 CHCl > (CH 3 ) 3 CCl, (CH 3 ) 2 CHCl > CH 3 CH 2 Cl > CH 3 Cl > (CH 3 ) 3 CCl

MARKS App · Accepted Answer

S N 2 involves the formation of a pentavalent intermediate, and the reactivity depends on steric hindrance. Lesser the steric hindrance, more is the reactivity of S N 2 .
