  1. Question 1

    Q1. A student compares the stability of cis-2-butene and trans-2-butene and finds the trans-isomer is more stable. The primary reason for this is:

    • A) Greater dipole moment
    • B) Higher boiling point
    • C) Less steric repulsion between methyl groups
    • D) More steric hindrance

    Answer: Less steric repulsion between methyl groups

    Explanation: Trans-2-Butene is more stable than cis-2-Butene due to less steric repulsion. Cis-isomers are tempting but have groups on the same side.
