MCQ
In $Fe ( CO )_{5},$ the $Fe - C$ bond possesses
- Aionic characters
- B$\sigma$ - character only
- C$\pi-$ character
- ✓Both $\sigma$ and $\pi$ characters
✓
Answer
Correct option: D.
Both $\sigma$ and $\pi$ characters
d
The $Fe - C$ bond has $\sigma$ and $\pi$ characteristics because of some back- bonding between $d$ $-$ orbital of metal and $p$ $-$ oribital of carbon.
