Ask EduPadi AI for a detailed answer
Correct Option: A

Alkanals, also known as aldehydes, are organic compounds that have a carbonyl group (C=O) bonded to a hydrogen atom and are located at the end of a carbon chain. The general structure of an alkanal is RCHO, where R represents an alkyl group.

Therefore, the correct answer is: Carbonyl group (C=O).
