  1. Question 1

    Q1. A laboratory technician compares the rate of nucleophilic addition between different carbonyl compounds. Which compound reacts most rapidly due to minimal steric hindrance and electronic effects?

    • A) Ethanal
    • B) Formaldehyde
    • C) Propanone
    • D) Butanone

    Answer: Formaldehyde

    Explanation: Formaldehyde lacks alkyl groups, making its carbonyl carbon more electrophilic than ethanal, which has a destabilizing electron-donating methyl group.
