  1. Question 1

    Q1. What fundamental condition for geometric isomerism contrasts it with the structural isomerism found in simple alkanes?

    • A) Structural isomerism requires a carbon-carbon double bond
    • B) Geometric isomerism occurs due to free rotation around sigma bonds
    • C) Geometric isomerism occurs due to restricted rotation around a pi bond
    • D) Structural isomerism is only possible in cyclic compounds

    Answer: Geometric isomerism occurs due to restricted rotation around a pi bond

    Explanation: Geometric isomerism requires a double bond to prevent rotation, while structural isomers can exist with only single bonds allowing free rotation.
