Benzaldehyde (\( \text{C}_6\text{H}_5\text{CHO} \)) can be reduced to 3-phenylpropanol using phenylmagnesium bromide (\( \text{C}_6\text{H}_5\text{MgBr} \)), a Grignard reagent. The reaction involves nucleophilic attack on the carbonyl group by the Grignard reagent, followed by hydrolysis to form 3-phenylpropanol.
