Question : 87 of 100

Marks: +1, -0

$\mathrm{PEt_3}$ and $\mathrm{AsPh_3}$ as ligands can form $\mathrm{d}\pi$ - $\mathrm{d}\pi$ bond with transition metals
The $\mathrm{N}-\mathrm{N}$ single bond is as strong as the $\mathrm{P}-\mathrm{P}$ single bond
Nitrogen has unique ability to form $\mathrm{p}\pi-\mathrm{p}\pi$ multiple bonds with nitrogen, carbon and oxygen
Nitrogen cannot form $\mathrm{d}\pi$ - $\mathrm{p}\pi$ bond as other heavier elements of its group

Solution:

● PEts and

\mathrm{AsPh_3}

as ligands can form

\mathrm{d}\pi-\mathrm{d}\pi

bond with transition metals.

● The

\mathrm{N}-\mathrm{N}

single bond is weaker than the single

\mathrm{P}-\mathrm{P}

bond because of high inter-electronic repulsion of the non-bonding electrons.

● Nitrogen has unique ability to form

\mathrm{p}\pi-\mathrm{p}\pi

multiple bonds with itself, carbon and oxygen.

● Nitrogen cannot form

\mathrm{d}\pi-\mathrm{p}\pi

bond as other heavier elements of its group.
