JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure / रासायनिक आबंधन एवं आणविक संरचना Question Bank Polarisation and Fajan's rule

  • question_answer
    Two electrons of one atom A and two electrons of another atom B are utilized to form a compound AB. This is an example of                                            [MNR 1981]

    A)                 Polar covalent bond       

    B)                 Non-polar covalent bond

    C)                 Polar bond         

    D)                 Dative bond

    Correct Answer: A

    Solution :

                    When two atoms shares two electrons it is an example of covalent bond. This covalent bond may be polar or may be non-polar depends on the electronegativity difference. In given example formula is AB. So it is polar.
