Identify the major organic product formed in the following reaction.

Step-by-step solution

The reactant is a molecule containing both a ketone group ( -C(=O)- ) and a cyano group ( -C N ). Grignard reagents ( CH₃MgBr ) are strong nucleophiles and will react with both electrophilic centers: the carbonyl carbon and the cyano carbon. Reaction at the ketone group: The methyl nucleophile ( CH₃^- ) attacks the carbonyl carbon, opening the C=O double bond to form a tetrahedral alkoxide intermediate. Upon acidic workup ( H₃O^+ ), this alkoxide is protonated to form a tertiary alcohol. Since the original ketone h
