Which of the following carbonyls will have the strongest C ‐ O bond?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The presence of positive charge on the metal carbonyl would resist the flow of the metal electron charge to 
orbitals of 
. This would increase the 
bond order and hence 
in a metal carbonyl cation would absorb at a higher frequency compared to its absorption in a neutral metal carbonyl.
