$2,2-$dimethyltetrahydrofuran

Vedclass · Answer

(C) The reaction proceeds in two steps:$1$. The Grignard reagent $CH_3MgBr$ acts as a nucleophile and attacks the carbonyl carbon of $5-chloropentan-2-one$. This forms an alkoxide intermediate.$2$. Upon workup with $H_3O^+$,the alkoxide oxygen is protonated to form an alcohol. However,in the presence of the internal chloride group,the alkoxide oxygen performs an intramolecular nucleophilic substitution $(S_N2)$ reaction,displacing the chloride ion to form a five-membered cyclic ether,$2,2-dimethyltetrahydrofuran$.

In the following reaction,the major product $(H)$ is
