  1. Question 1

    Q1. During the free-radical polymerization of ethene, an organic peroxide is added to the reaction mixture. What is the specific role of this peroxide?

    • A) Chain terminator
    • B) Reaction inhibitor
    • C) Polymerization initiator
    • D) Solvent medium

    Answer: Polymerization initiator

    Explanation: Peroxides generate free radicals to start the reaction; inhibitors are tempting but they actually stop or slow the polymerization process.
