  1. Question 1

    Q1. In the reaction with magnesium to form Grignard reagents, which alkyl halide demonstrates the highest rate of reaction due to bond weakness?

    • A) R-F
    • B) R-Cl
    • C) R-Br
    • D) R-I

    Answer: R-I

    Explanation: The C-I bond is the weakest and easiest to break during magnesium insertion; R-Br is tempting because it is most commonly used commercially.
