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