Which of the following can be reduced easily?
Options
- AV ( CO )₆
- BMo ( CO )₆
- C[ Co ( CO )₄ ]⁻
- DFe ( CO )₅
Correct answer
A. V ( CO )₆
Step-by-step solution
V ( CO )₆ can be easily reduced to [ V ( CO )₆ ]⁻ . V ( CO )₆ has a total of 17 bonding electrons, hence it is very reactive and unstable. [ V ( CO )₆ ] on the other hand has complete set of 18 bonding electrons as an electron is added into the bonding orbital when V ( CO )₆ gets reduced to [ V ( CO )₆ ]⁻ . All others have 18 bonding electrons.
