  1. Question 1

    Q1. In a molecule of propanone, what is the approximate bond angle around the central carbonyl carbon atom?

    • A) 120 degrees
    • B) 109.5 degrees
    • C) 180 degrees
    • D) 90 degrees

    Answer: 120 degrees

    Explanation: Carbonyl carbon is sp2 hybridized with 120-degree bond angles. 109.5 is tempting but refers to sp3 hybridization.
