How is the M–C s bond formed in metal carbonyls?
Options
- ABy the donation of a pair of electrons from a filled d orbital of metal
- BBy the donation of a lone pair of electrons on the carbonyl carbon into a vacant orbital of the metal
- CBy the donation of a pair of electrons from the metal into the vacant antibonding p* orbital of carbon monoxid
- DBy the donation of a pair of electrons from a filled p orbital of metal into the vacant orbital of the carbon
Correct answer
B. By the donation of a lone pair of electrons on the carbonyl carbon into a vacant orbital of the metal
Step-by-step solution
The M–C s bond is formed by the donation of a lone pair of electrons on the carbonyl carbon into a vacant orbital of the metal.
