Which of the following is a functional group commonly found in alcohols?
A
Hydroxyl group (-OH)
B
Amino group (-NH2)
C
Carbonyl group (C=O)
D
Carboxyl group (-COOH)
Verified step by step guidance1
Identify the functional groups listed in the options: Hydroxyl group (-OH), Amino group (-NH2), Carbonyl group (C=O), and Carboxyl group (-COOH).
Recall the definition of an alcohol in organic chemistry: Alcohols are organic compounds where a hydroxyl group (-OH) is bonded to a carbon atom.
Understand that the presence of a hydroxyl group (-OH) is the defining feature of alcohols, distinguishing them from other organic compounds.
Compare the functional groups provided in the options with the definition of alcohols to determine which group is commonly found in alcohols.
Conclude that the hydroxyl group (-OH) is the functional group commonly found in alcohols, as it matches the defining characteristic of alcohols.
