Vedclass · Answer

(B) The sulfonation of $\alpha$-tetralone is an electrophilic aromatic substitution reaction.$\alpha$-tetralone consists of a benzene ring fused to a cyclohexanone ring.The carbonyl group $(-C=O)$ is a deactivating and meta-directing group.However,in the case of $\alpha$-tetralone,the electronic effects and steric factors influence the regioselectivity.The sulfonation of $\alpha$-tetralone primarily occurs at the $6$-position due to the combined electronic effects of the fused ring and the carbonyl group,which makes the $6$-position the most nucleophilic site for electrophilic attack.Therefore,the major product is the $6$-sulfonic acid derivative of $\alpha$-tetralone.

Which of the following is the major product from the sulfonation of $\alpha$-tetralone?
