Which of the following is incorrect for addition polymerisation?

Options

A. In this type of polymerisation, the molecules of the same monomer of different monomers simply add together on a large scale to from a polymer
B. The monomers used are unsaturated compounds
C. This mode of polymerisation can take place only through formation of free radicals
D. This process of polymerisation is also called chain growth polymerisation is also called chain growth polymerisation

Answer

C

Explanation

This mode of polymerisation can take place through formation of either radicals or ionic species such as carbon ions or carbocation. However, the free radical governed addition polymersiation is the most common mode. This process which involves unsturated compounds such as alkenes, alkadines and their derivatives is aslo called chain growth polymerisation because it takes place through stages leading to increase of chain length and each stage produces reactive intermediate for use in the next stage of the growth of the chain.
