Which of the following complexes or molecules has/ have N-N bond length greater than that in free `N_(2)` molecule?

A

`[Ru(NH_(3))_(5)(N_(2))]^(+)`

B

`[Ni(Pme_(3))_(3)(N_(2))]`

C

`[CoH(PPh_(3))_(3)(N_(2))]`

D

`N_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
In (a),(b),(c ) N-B.L.`uarr` due to synergic bonding while in `N_(2)O`,B.L.`uarr` due to resonance.
