Question

What is a monomer?

• A. Are always unsaturated molecules that make polymers.
• B. Smallest repeating units of polymers
• C. Molecules with at least 3 carbons atoms.
• D. Molecules with a single carbon atoms indicating mono.

Answer 1

The correct option is B Smallest repeating units of polymers

Monomers are the smallest, repeating units that make up polymers. For example, ethene is the monomer for polyethene.

Monomers need not always be unsaturated. Addition polymers have unsaturated monomer units. But condensation polymers usually don't.
