  1. Question 1

    Q1. In a laboratory analysis of 2-butene isomers, how do the physical properties of the cis-isomer typically contrast with the trans-isomer?

    • A) Cis-isomers always have higher melting points
    • B) Trans-isomers have higher dipole moments than cis-isomers
    • C) Cis-isomers generally have higher boiling points
    • D) Cis and trans isomers have identical physical properties

    Answer: Cis-isomers generally have higher boiling points

    Explanation: Cis-isomers are generally polar with higher boiling points, while trans-isomers are less polar or non-polar with higher melting points due to symmetry.
