Which of the following has longest C-O bond length? (Free C-O bond length in CO is 1.128 .)
Multiple Choice Options
- A [Fe(CO) 4 ] 2 _
- B [Mn(CO) 6 ] +
- C Ni(CO) 4
- D [Co(CO) 4 ] _
Step-by-Step Verified Solution
[Fe(CO) 4 ] 2 _ has the lowest C�O bond order means the longest bond length.
Since metal atom is carrying maximum �ve charge therefore it would show maximum synergic bonding as a resultant C�O bond length would be maximum.
