  1. Question 1

    Q1. During a comparative laboratory test, four different ethyl halides are reacted with a nucleophile. Which compound will exhibit the highest rate of reactivity?

    • A) Ethyl fluoride
    • B) Ethyl chloride
    • C) Ethyl bromide
    • D) Ethyl iodide

    Answer: Ethyl iodide

    Explanation: Iodides have the lowest bond energy, making them most reactive. Fluorides are tempting due to high polarity, but bond strength determines reactivity.
