Question

Which of the following has greater polarizability?

Options
  • A

    N2

  • B

    Cl2

  • C

    O2

  • D

    I2

Explanation

OPTION A: In comparison, N2 (Nitrogen) has a smaller size and fewer electrons, making it less polarizable.

OPTIONS B, C: Cl2 (chlorine) and O2 (oxygen) have intermediate polarizabilities, with Cl2 being more polarizable than O2 due to its larger size and more electrons.

OPTION D: Iodine has greater polarizability than the other options because it has a larger atomic size and more electrons. This results in a larger electron cloud, making it more susceptible to changes in an electric field.
