Vedclass · Answer

(A) The given reaction is a Hofmann elimination reaction.In this reaction,a quaternary ammonium hydroxide is heated,leading to the formation of an alkene and a tertiary amine.The hydroxide ion $(OH^-)$ acts as a base and abstracts a proton from the $\beta$-carbon atom of the alkyl group attached to the nitrogen.According to the Hofmann rule,the less substituted alkene is formed as the major product.In the given reactant,the alkyl groups attached to the nitrogen are one propyl group $(CH_3CH_2CH_2-)$ and three ethyl groups $(-CH_2CH_3)$.When the base abstracts a proton from the $\beta$-carbon of an ethyl group,ethene $(H_2C=CH_2)$ is formed as the alkene product $A$.

Identify the product $A$ in the following reaction:
$[(CH_3CH_2CH_2)(CH_3CH_2)_3N]^+ OH^- \xrightarrow{\Delta, -H_2O} A + (CH_3CH_2CH_2)(CH_3CH_2)_2N$
