Amine
B
Aldehyde
C
Alcohol
D
Ether
Verified step by step guidance1
Identify the functional group in question: The problem asks for a functional group characterized by a carbon atom double-bonded to an oxygen atom.
Understand the structure: A carbon atom double-bonded to an oxygen atom is known as a carbonyl group, represented as .
Review the options: Examine each option to determine which contains a carbonyl group. Amine, Alcohol, and Ether do not contain a carbonyl group.
Focus on Aldehyde: An aldehyde is characterized by a carbonyl group bonded to a hydrogen atom and an R group (which can be a hydrogen or a hydrocarbon chain), represented as .
Conclude: Based on the structure, the correct answer is Aldehyde, as it contains the carbonyl group described in the problem.
