  1. Question 1

    Q1. During the formation of ethene (C2H4), each carbon atom undergoes sp2 hybridization. What is the expected H-C-H bond angle in this molecule?

    • A) 109.5 degrees
    • B) 120 degrees
    • C) 180 degrees
    • D) 104.5 degrees

    Answer: 120 degrees

    Explanation: The sp2 geometry is trigonal planar with 120-degree angles. Option A fails because 109.5 degrees is characteristic of tetrahedral sp3 hybridization.
