  1. Question 1

    Q1. A 1.47 g sample of an organic halide yields 2.87 g of AgCl in Lassaigne's test. What is the percentage of chlorine in the compound?

    • A) 35.5%
    • B) 24.1%
    • C) 48.3%
    • D) 71.0%

    Answer: 48.3%

    Explanation: Calculated from chlorine mass in AgCl relative to sample. 35.5% is wrong, confusing atomic mass with actual percentage.
