Benzoic Acid vs. Benzaldehyde: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 9, 2024
Benzoic acid is a carboxylic acid with a formula C6H5COOH, used as a food preservative, while benzaldehyde is an aromatic aldehyde, C6H5CHO, used as a flavoring agent.

Key Differences

Benzoic acid, with the chemical formula C6H5COOH, features a carboxyl group attached to a benzene ring. Benzaldehyde, denoted as C6H5CHO, contains an aldehyde group attached to a benzene ring. Their different functional groups lead to different chemical properties.
