उत्तर
A primary alkyl halide would prefer to undergo SN2 reaction.
Explanation:
SN2 type reactions (i.e. bimolecular nucleophilic substitution) proceed in one step and the rate of reaction depends on concentration of alkyl halide as well as nucleophile i.e. r = k[RX][Nu]. It is a second-order reaction. During SN2 reaction, inversion in configuration occurs (viz. starting with dextrorotatory halide a laevorotatory product is obtained and vice-versa).
