  1. Question 1

    Q1. A student observes the molecular geometry of a propanone molecule during a modeling session. What is the approximate bond angle around the carbonyl carbon?

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

    Answer: 120 degrees

    Explanation: The carbonyl carbon is sp2 hybridized, creating a trigonal planar arrangement with 120-degree angles. Option A represents sp3 tetrahedral geometry incorrectly.
