  1. Question 1

    Q1. Comparing the geometry of ethane and ethene molecules, what is the characteristic bond angle associated with the carbon atoms in ethene?

    • A) Ethane has a bond angle of 120 degrees
    • B) Ethene has a bond angle of 109.5 degrees
    • C) Ethane has a bond angle of 180 degrees
    • D) Ethene has a bond angle of 120 degrees

    Answer: Ethene has a bond angle of 120 degrees

    Explanation: In sp3 hybridization (alkanes), the bond angle is 109.5°, while in sp2 (alkenes), it is 120° due to planar geometry.
