The chemical compound benzaldehyde (C6H5CHO) consists of a benzene ring with an aldehyde group attached to one carbon. It is an important component of the scent of almonds and has a pleasant, almond-like odor. On oxidation, benzaldehyde is converted into benzoic acid, which has an odor quite unpleasant. Hydrogenation of benzaldehyde forms benzyl alcohol or phenylmethanol.
