The correct answer is d) Amino group (-NH2).
Step-by-step explanation:
The correct answer is d) Amino group (-NH2).
An amino group (-NH2) is a functional group that can bond with carbon. The other options, hydroxyl group (-OH), carbonyl group (C=O), and carboxyl group (-COOH) are all functional groups that can bond with carbon.
Functional groups are groups of atoms that give specific properties to organic compounds. They are responsible for the unique characteristics and functions of different organic molecules.
