  1. Question 1

    Q1. Why do reactions with higher activation energy typically proceed through multi-step mechanisms?

    • A) They require multiple electron rearrangements
    • B) They generate unstable transition states with high electron energy
    • C) They involve multiple bond breaking/forming steps
    • D) They require catalysts with specific electron configurations

    Answer: They involve multiple bond breaking/forming steps

    Explanation: Multi-step mechanisms lower the overall activation barrier. Electron energy and catalysts are secondary factors.
