    Which of the following is a polar compound         [AIIMS 2001]

    A)                 HF          

    B)                 HCl

    C)                 \[HN{{O}_{3}}\]               

    D)                 \[{{H}_{2}}S{{O}_{4}}\]

    Correct Answer: A

    Solution :

                    We know that greater the difference in electronegativity of two atoms forming a covalent bond. More is its polar nature. In HF there is a much difference in the electronegatives of hydrogen and flourine. Therefore (HF) is a polar compound.
