MCQ
Which of the following complex has highest $C-O$ bond length ?
- A$[Ni(CO)_3(PF_3)]$
- B$[Ni(CO)_4]$
- ✓$[Ni(CO)_3(PMe_3)]$
- DNone
✓
Answer
Correct option: C.
$[Ni(CO)_3(PMe_3)]$
c
In $[Ni(CO)_3(PMe_3)]$ extent of synergic bonding towards $CO$ will be maximum. So $C-O$ bond order will be minimum hence $C-O$ bond length will be maximum
