The principal structural difference between an aldehyde and a ketone is to be stated. Concept introduction: A carbonyl group has a carbon atom that is bonded to an oxygen atom through a double bond and single bonded to two other carbon atoms respectively. Aldehydes and ketones contain carbonyl functional group in their parent chain and are named by adding suffix –al and –one to the name of the parent alkane .

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Expert Solution & Answer
Answer to Problem 14.1E
The structural formula of an aldehyde is R−CO−H.
The structural formula of a ketone is R−CO−R.
Explanation of Solution
An aldehyde consists of a carbonyl group that is single bonded to minimum one hydrogen atom, whereas a ketone consists of a carbonyl group that is single bonded to two carbon atoms. The structure difference between an aldehyde and a ketone is shown below.
