The structural formulas is to be drawn for each of the following species. Concept introduction: Aldehyde and ketones are organic compounds. They contain carbonyl functional group . Aldehyde has a structure − CHO , consisting of a carbonyl centre (a carbon double bonded to oxygen) with the carbon atom also bonded to hydrogen and to a R group which is any alkyl or side chain. In a ketone, two carbon groups are attached to the carbonyl carbon atom. To determine: The structural formula of formaldehyde ( methanal ) .

Solution Summary: The author explains that the structural formulas are to be drawn for each of the following species.
Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.
