Identify the incorrect statement. (1) PEt3 and AsPh3 as ligands can form dπ-dπ bond with transition metals

Question

Identify the incorrect statement. 

(1) \(PEt_3\) and \(AsPh_3\) as ligands can form \(d\pi-d\pi\) bond with transition metals 

(2) The N – N single bond is as strong as the P – P single bond 

(3) Nitrogen has unique ability to form \(p\pi-p\pi\) multiple bonds with nitrogen, carbon and oxygen 

(4) Nitrogen cannot form \(d\pi-p\pi\) bond as other heavier elements of its group

Answer 1

Correct option is (2) The N – N single bond is as strong as the P – P single bond 

\(PEt_3\) and \(AsPh_3\) as ligands can form \(d\pi-d\pi\) bond with transition metals. 

The N – N single bond is weaker than the single P – P bond because of high inter-electronic repulsion of the non-bonding electrons. 

Nitrogen has unique ability to form \(p\pi-p\pi\) multiple bonds with itself, carbon and oxygen. 

Nitrogen cannot form \(d\pi-p\pi\) bond as other heavier elements of its group.
