  1. Question 1

    Q1. In the presence of 50% NaOH, certain aldehydes undergo self-oxidation-reduction. Which of the following aldehydes will participate in this Cannizzaro reaction?

    • A) Ethanal
    • B) Propanal
    • C) 2,2-Dimethylpropanal
    • D) 3-Methylbutanal

    Answer: 2,2-Dimethylpropanal

    Explanation: Cannizzaro reaction occurs in aldehydes lacking alpha-hydrogens, like benzaldehyde. Option A fails because ethanal has alpha-hydrogens and undergoes aldol.
