  1. Question 1

    Q1. When Formaldehyde is treated with 50% Sodium Hydroxide, it undergoes a specific transformation. What is the nature of this chemical process according to PTB?

    • A) Formation of an Aldol
    • B) Dehydration to an alkene
    • C) Substitution of the alpha-hydrogen
    • D) Self oxidation-reduction

    Answer: Self oxidation-reduction

    Explanation: Cannizzaro reaction is a disproportionation where one molecule reduces to an alcohol and another oxidizes to a salt. Aldol condensation produces beta-hydroxy aldehydes.
