One of the most important uses for Grignard reagents is their addition to carbonyl compounds to give new carbon-carbon bonds. In this reaction, the carbon of the organometallic compound acts as a nucleophile to add to the positive carbon of the carbonyl forming an alkoxide ion intermediate. Aqueous acid is used in the second step to protonate the alkoxide ion and form the product alcohol. Draw the structure of the product(s) of step 1 when the following compound reacts with...
