10.9:Which compound in each of the following pairs will react faster in SN2 reaction with –OH? (i) CH3Br or CH3I (ii) (CH3)3CCl or CH3Cl
Rate of SN2 reaction depends on steric hindrance around target atom. As CH3I provides less hindrance, it will react faster by SN2 reaction than CH3Br. CH3Cl being primary halide provides less hindrance to action of OH-, thus it will react by SN2 more easily than (CH3)3CCl.
