The image shows a chemical reaction where an aldehyde reacts with a Grignard reagent. Grignard reagents (R-MgBr) are nucleophiles that attack the carbonyl carbon of aldehydes. After nucleophilic addition, the intermediate is hydrolyzed to form a secondary alcohol. The general reaction is:

$R-\mathrm{CHO}+R_1\mathrm{MgBr}\to \mathrm{Hydrolysis}\to R-\mathrm{CH}\left(\mathrm{OH}\right)-R_1$

Final Answer: The product is a secondary alcohol.
