Question

Small molecules like water, ammonia, etc. are released during polymerisation.

• A. addition
• B. condensation
• C. homo

Answer 1

The correct option is B condensation

Condensation polymerisation occurs when monomers containing different functional groups join together to form a repeating unit which in turn forms a polymer. During this, small molecules like water $\left(H_{2}O\right)$, ammonia $\left(N{H}_3\right)$, etc. are eliminated.

During addition polymerisation, the monomers simply join together to form the repeating units, without elimination of any small molecule. Homopolymerisation is a type of addition polymerisation.
