Compound X reacts with Grignard's reagent to produce tertiary alcohols. What is the compound?
Correct answer: B. Ketone
- A. Aldehyde
- B. Ketone
- C. Acid halide
- D. Carboxylic acid
Explanation
Grignard's reagent (RMgX) reacts with ketones to produce tertiary alcohols. The reaction involves the nucleophilic addition of the Grignard reagent to the carbonyl group of the ketone, followed by hydrolysis to form a tertiary alcohol.The reaction is:R2C=O (ketone) + RMgX (Grignard reagent) → R2C(OH)R' (tertiary alcohol)

About Nucleophilic Addition Reactions
Nucleophilic addition occurs at the polar carbonyl group of aldehydes and ketones, where a nucleophile attacks the electron-deficient carbon atom. Reactions with hydrogen cyanide, sodium bisulfite, alcohols and Grignard reagents are explained through tetrahedral intermediates, acid or base catalysis, and the different reactivity of aldehydes and ketones.
