What type of molecule is a monomer?

• A. Double
• B. Single
• C. Complex
• D. Triple

Answer: (B)

A monomer is a single molecule that can join together with other similar molecules to form larger structures known as polymers. In the context of chemistry, monomers are the basic building blocks of these complex structures. For example, in the case of polymers like plastic or DNA, monomers link through chemical reactions to create long chains that exhibit different physical and chemical properties.

Focusing on the term “single,” it accurately reflects the fundamental nature of a monomer as it represents the simplest form of the molecule before it undergoes polymerization, where two or more monomers connect. Understanding this concept is essential for grasping how larger, more complex substances are formed in both natural and synthetic processes.
