Alkyl halides undergo nucleophilic substitution reactions in which halogen atom is replaced by other atom. RX + Nu:^(-) to Nu-R + X^(-) These reactions follow S_(N)1 and S_(N)2 type mechanism, in which S_(N)1 takes place in two steps while S_(N)2 takes place in single step. Due to their tendency to undergo substitution by a large number of nucleophiles, they form a variety of products. In which of the following pairs, the first compound is better S_(N)2 substrate ?
