Multiple Choice

Which of the following is a functional group commonly found in alcohols?

Carboxyl group (-COOH)

Hydroxyl group (-OH)

Amino group (-NH2)

Carbonyl group (C=O)

Verified step by step guidance

Identify the functional group associated with alcohols. Alcohols are characterized by the presence of a hydroxyl group.

Understand the structure of a hydroxyl group. It is represented as -OH, where an oxygen atom is bonded to a hydrogen atom.

Differentiate between the given options: Carboxyl group (-COOH), Hydroxyl group (-OH), Amino group (-NH2), and Carbonyl group (C=O).

Recognize that the hydroxyl group (-OH) is the functional group that defines alcohols, as it is directly bonded to a carbon atom in the carbon chain.

Conclude that among the options provided, the hydroxyl group (-OH) is the correct functional group commonly found in alcohols.
