  1. Question 1

    Q1. Phenol is more acidic than ethanol due to its ability to form a resonance-stabilized anion. What is the consequence of this stabilization on the acid strength of phenol?

    • A) Phenol is a stronger acid than ethanol
    • B) Phenol is a weaker acid than ethanol
    • C) Phenol and ethanol have equivalent acid strengths
    • D) Phenol has a higher pKa value than ethanol

    Answer: Phenol is a stronger acid than ethanol

    Explanation: The resonance stabilization of the phenoxide anion increases the acidity of phenol, making it stronger than ethanol.
