Question

Consider the free radical addition polymerization of ethene. The termination step completely halts the growth of the macroradical. Which of the following specific chemical reactions correctly represents a standard termination mechanism?

Prashant Kotian · Accepted Answer

Correct answer: C. Radical chains standardly terminate by either direct combination (coupling of two radicals) or disproportionation. Backbiting is a transfer mechanism that causes branching, not termination.
