Vedclass · Answer

(D) The reaction is a Hofmann elimination of a quaternary ammonium hydroxide. In Hofmann elimination,the base $(OH^{-})$ abstracts a proton from the $\beta$-carbon that is least sterically hindered. The possible $\beta$-hydrogens are on the cyclohexyl ring,the ethyl group,and the $n$-butyl group. The transition state for the formation of the least substituted alkene is favored due to steric hindrance. Among the alkyl groups attached to the nitrogen,the ethyl group has the most accessible $\beta$-hydrogens. Therefore,the elimination of the ethyl group leads to the formation of ethene $(CH_2=CH_2)$ as the major product.

Identify the major product of the following Hofmann elimination reaction: $[\text{cyclohexyl-}N^{+}(CH_3)(CH_2CH_3)(n\text{-Bu})]OH^{-} \xrightarrow{\Delta} \text{Major product}$
