What is the product of the reaction between an aldehyde and a Grignard reagent?

Correct Answer: Secondary alcohol

Step 1: Identify the aldehyde and the Grignard reagent. An aldehyde has the structure RCHO, where R is a hydrocarbon group.
Step 2: The Grignard reagent has the structure RMgX, where R is a hydrocarbon group and X is a halogen (like Cl, Br, or I).
Step 3: When the Grignard reagent is added to the aldehyde, it reacts with the carbonyl carbon (C=O) of the aldehyde.
Step 4: This reaction forms a new carbon-carbon bond, resulting in an intermediate compound called an alkoxide.
Step 5: The alkoxide is then treated with water (hydrolysis), which converts it into a secondary alcohol.
Step 6: The final product is a secondary alcohol, which has the structure R2CHOH, where R is the hydrocarbon group from the aldehyde and the Grignard reagent.
