Cyanides.<\/p>\n<p>Functional group isomerism is a type of isomerism in which two or more compounds have the same molecular formula but different functional groups. In cyanides, the functional group is the cyanide group (CN). The cyanide group is always present in cyanides, so functional group isomerism is not possible.<\/p>\n<p>Alcohols have the functional group hydroxyl (-OH). Aldehydes have the functional group aldehyde (-CHO).
