Predict the product(s) for the following reaction.

Question

Quizplus · Accepted Answer

The reaction is a substitution reaction where Br is replaced with CN. The mechanism for the reaction is SN2 due to the good leaving ability of Br and the high nucleophilicity of CN-. The reaction will result in the formation of products I and III, where the CN- replaces the Br atom in the 1- and 3-positions of the molecule, respectively. The other products (II, IV, and V) are not formed because they either violate the rules of organic chemistry or require unlikely mechanisms.
