  1. Question 1

    Q1. Phenol reacts readily with aqueous sodium hydroxide to form a salt, whereas ethanol shows no reaction. What explains this difference in chemical behavior?

    • A) Inductive effect of ethyl
    • B) Steric hindrance in phenol
    • C) Resonance stabilization of phenoxide
    • D) Hydrogen bonding in ethanol

    Answer: Resonance stabilization of phenoxide

    Explanation: Phenoxide ion is stabilized by resonance of the negative charge over the benzene ring, making phenol significantly more acidic than ethanol.
