Verified step by step guidance1
Step 1: Understand the definition of a functional group. In organic chemistry, a functional group is a specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
Step 2: Identify the functional groups listed in the problem. The options given are: Carbonyl group (C=O), Amino group (-NH2), Carboxyl group (-COOH), and Hydroxyl group (-OH).
Step 3: Recall the structure of alcohols. Alcohols are organic compounds where a hydroxyl group (-OH) is bonded to a carbon atom.
Step 4: Compare the functional groups listed with the structure of alcohols. Alcohols contain the hydroxyl group (-OH), which is responsible for their properties and reactions.
Step 5: Conclude that the functional group present in alcohols is the hydroxyl group (-OH), as it matches the characteristic structure of alcohols.
