WebThe aryl aldehyde is less reactive than an aliphatic aldehyde. Consequently, the aryl aldehyde is less likely to react with free amines to form a Schiff base. Moreover, a Schiff base between an aryl aldehyde and a free amine is easily reversed. This means that the aldehyde is free to react with a hydrazide or oxyamine group. WebAldehydes and Ketones. Both aldehydes and ketones contain a carbonyl group, a functional group with a carbon-oxygen double bond.The names for aldehyde and ketone compounds are derived using similar nomenclature rules as for alkanes and alcohols, and include the class-identifying suffixes -al and -one, respectively:.
