  1. Question 1

    Q1. If 1.0 mole of Benzaldehyde undergoes a Cannizzaro reaction with concentrated NaOH, how many moles of Benzyl alcohol will be theoretically produced?

    • A) 0.5 moles
    • B) 1.0 moles
    • C) 2.0 moles
    • D) 0.25 moles

    Answer: 0.5 moles

    Explanation: Cannizzaro reaction is a disproportionation; 2 moles of Benzaldehyde produce 1 mole of Benzyl alcohol and 1 mole of Sodium Benzoate. Option B ignores stoichiometry.
