MCQ
The common features among the species $C{N^ - }$, $CO$ and $N{O^ + }$ are
- ✓Bond order three and isoelectronic
- BBond order three and weak field ligands
- CBond order two and $\pi$-acceptors
- DIsoelectronic and weak field ligands
✓
Answer
Correct option: A.
Bond order three and isoelectronic
(a) Each of the species has $14$ electron so isoelectronic and shows bond order $3.$
$B.O.$$ = \frac{1}{2}[{N_b} - {N_a}]$$ = \frac{1}{2}[10 - 4] = \frac{6}{2} = 3$.
