Solution
This reaction involves forming a Grignard reagent from a monochloro derivative (R-Cl) with Mg in dry ether: . This reagent then reacts with the given cyclic ketone (cyclopentanone). The Grignard reagent acts as a nucleophile, attacking the carbonyl carbon. This forms a new C-C bond and, after hydrolysis, yields a tertiary alcohol. The major product is the tertiary alcohol derived from cyclopentanone.
