JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure Question Bank Dipole moment

  • question_answer Dipole moment is shown by        [IIT 1986]

    A)                 1, 4-dichlorobenzene    

    B)                 \[cis\] 1, 2-dichloroethene

    C)                 \[trans\]1, 2-dichloroethene

    D)                 \[trans\]1, 2-dichloro-2-pentene

    Correct Answer: B

    Solution :

                    cis isomer shows dipole moment while that of trans is zero or very low value. Trans 1, 2 di-chloro-2-pentene will also show dipole moment due to unsymmetry.
