  1. Question 1

    Q1. A student attempts to purify various carbonyl compounds using saturated sodium bisulfite. Which compound will show no reaction despite having a carbonyl group?

    • A) Formaldehyde
    • B) Acetone
    • C) Diethyl ketone
    • D) Acetaldehyde

    Answer: Diethyl ketone

    Explanation: Higher ketones like diethyl ketone cannot form bisulfite adducts due to steric hindrance. Acetone reacts easily because its methyl groups are relatively small.
