This reaction would follow which of the following pathway predominantly?

HI is very strong acid consequently, by Bronsted Lowry, I is very weak base. Thus elimination is out of question. Similarly, the halide being primary, N S 2 takes place. 42. Which among MeX, RCH2X, R2CHX, R3CX is most reactive towards SN2reaction? (a) MeX (b) RCH2X (c) R2CHX (d) R3CX N S 2 reaction means nucleophilic substitution bi- molecular reaction. This reaction takes place when the leaving group is attached to the primary carbon atom. As the number of substituents on the carbon atom carrying halogen increases, steric hindrance increases and hence the rate of SN2 reaction decreases. H
