  1. Question 1

    Q1. A chemist is testing various unsaturated compounds for geometric isomerism but finds that 2-butyne fails the test. This is primarily because:

    • A) Presence of a double bond
    • B) Lack of hydrogen atoms
    • C) Restricted rotation
    • D) Linear geometry around the triple bond

    Answer: Linear geometry around the triple bond

    Explanation: 2-Butyne cannot show cis-trans isomerism because the geometry is linear around the triple bond. 2-Butene is tempting as it shows isomerism.
