Question
Which of the following has longest C - O bond length? (Free C - O bond length in CO is 1.128 ).
Options
A.
Ni(CO)4
B.
C.
[Fe(CO)4]2-
D.
[Mn(CO)6]+
Solution
Metal carbon bond in metal carbonyls possess both and character. M - C bond is formed by donation of a pair of electrons from filled orbital of metal into vacant antibonding π orbital of CO. CO bond length increases if M has more tendency to donate lone pair by metal more CO bond length.
