Question

What is the major organic product obtained from the following reaction?

Answer 1

First, it may be helpful to name the main reactant molecule. This is a benzene ring derivative, where there is an aromatic ring, C6H5, with a substituent attached off one of its carbon's instead of just a Hydrogen atom.

This is called Propyl Benzene, a benzene ring with a propyl group attached.

N-Bromosuccinimide (NBS) is a brominating and oxidizing agent that is used as source for bromine in radical reactions (for example: allylic brominations) and various electrophilic additions.

Acetone is categorized as a very weak acid, and NaCN may ionize forming Na+ and CN- or cyanide ion in solution which gets protonated if the weak acid, acetone happens to deprotonate depending on pH and solution conditions, forming HCN which may nucleophilically attach the propyl benzene.

Hope this helps in determining your major product(s) formed from this reaction!
