Answer 2

Answer:

C

Explanation:

Correct option is

C

Nitrogen

Nitrogen forms Pπ−Pπ multiple bonds.

In diatomic :N≡N:, 1 bond is sigma and the remaining 2 bonds are Pπ−Pπ bonds.

Other elements of group 15 do not form Pπ−Pπ multiple bonds due to repulsion between non bonded electrons of the inner core and size.

There is no such repulsion in case of smaller nitrogen atoms as they have only 1s

2

electrons in their inner core and hence, their p orbitals easily overlap to form Pπ−Pπ multiple bonds.
