WebIt reduces everything, including the C=C bond. If you add the LiAlH4 slowly to the aldehyde, the aldehyde is always in excess. The relatively small amount of LiAlH4 present at any one time will reduce the most active groups (COOH and CHO) first. Once they have been reduced, you have only an isolated C=C bond remaining, and LiAlH4 does not ...
