Vedclass · Answer

(B) The given reaction is an elimination reaction of a quaternary ammonium salt $(CH_{3}CH_{2}CH_{2}CH(N^{+}(CH_{3})_{3})CH_{3})$ using a base $(C_{2}H_{5}ONa)$.This is an example of the Hofmann elimination reaction.In Hofmann elimination,the less substituted alkene is formed as the major product due to steric hindrance caused by the bulky leaving group $(N^{+}(CH_{3})_{3})$.Therefore,the terminal alkene $CH_{3}CH_{2}CH_{2}CH=CH_{2}$ is the major product $(A)$,and the internal alkene $CH_{3}CH_{2}CH=CHCH_{3}$ is the minor product $(B)$.
