N ₂ does not show property of catenation because

Options

  1. Ait has no d -orbitals in the valence shell
  2. Binterelectronic repulsion between non-bonding electrons is greater
  3. CN N has high bond enthalpy
  4. Dnitrogen has very high ionisation enthalpy

Correct answer

B. interelectronic repulsion between non-bonding electrons is greater

Step-by-step solution

Nitrogen does not show property of catenation. Since, N - N single bond is very weak due to large interelectronic repulsions between the lone pairs of electrons present on the N -atoms of N - N bond having small bond length.
