nitrogen

Vedclass · Answer

(D) Among the given group-$15$ elements,nitrogen can form multiple bonds with itself. Strong multiple bonds are formed only when the overlapping is effective,i.e.,overlapping orbitals are of similar energy and same symmetry. Nitrogen has a small size and has $2p$ orbitals (lower energy),which allows it to show $p\pi-p\pi$ bonding. Whereas,in the heavier elements,the overlapping orbitals are larger and have higher energy as atomic size increases down the group. Thus,in these cases,effective overlapping for $p\pi-p\pi$ bond does not take place.

The element that can form multiple bonds with itself from the following is
