Topic Question Set

Q 1 :

Identify the incorrect statement.             [2024]

  • PEt3 and AsPh3 as ligands can form dπ–dπ bond with transition metals.

     

  • The N—N single bond is as strong as the P—P single bond.

     

  • Nitrogen has unique ability to form pπ–pπ multiple bonds with nitrogen, carbon and oxygen.

     

  • Nitrogen cannot form dπ–pπ bond as other heavier elements of its group.

     

(2)

The single N—N bond is weaker than the single P—P bond because of high interelectronic repulsion of the non-bonding electrons, owing to the small bond length. As a result, the catenation tendency is weaker in nitrogen.
