Correct answer
B. 1-Ethylcyclohexan-1-ol
Step-by-step solution
The given reaction involves the nucleophilic addition of a Grignard reagent to a ketone. The Grignard reagent, ethylmagnesium bromide ( CH ₃ CH ₂ MgBr ), provides an ethyl carbanion ( CH ₃ CH ₂^- ) which acts as a nucleophile. It attacks the electrophilic carbonyl carbon of cyclohexanone, breaking the C=O bond to form a magnesium alkoxide intermediate. The acidic workup with H ₃ O ^+ protonates the alkoxide oxygen to yield the final tertiary alcohol product. The resulting molecule has a cyclohexane ring with both a
