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

  • question_answer Which of the following is a polar compound [Pb. CET 2000]

    A)                 \[HCl\] 

    B)                         \[{{H}_{2}}Se\]

    C)                 \[C{{H}_{4}}\]   

    D)                 \[HI\]

    Correct Answer: A

    Solution :

                    Higher is the difference in electronegativity of two covalently bonded atoms, higher is the polarity. In HCl there is high difference in the electronegativity of H and Cl atom so it is a polar compound.
