Sn2 reaction backside attack

WebVerified by Toppr. The S N. . 2 reaction involves displacement of a leaving group (usually a halide or tosylate), by a nucleophile. It is a one-step reaction. This reaction works the best with methyl and primary halides because bulky alkyl groups block the backside attack of the nucleophile, but the reaction does work with secondary halides ... WebThis reaction differs from a common S N 2 reaction, because it happens at a trigonal carbon atom (sp 2 hybridization).The mechanism of S N 2 reaction does not occur due to steric hindrance of the benzene ring. In order to attack the C atom, the nucleophile must approach in line with the C-LG (leaving group) bond from the back, where the benzene ring lies.
