Which of the following formula does not represent a metal carbonyl correctly?

A

`Mn_(2)(CO)_(10)`

B

(2) `Fe_(2)(CO)_(9)`

C

`Cr_(2)(CO)_(6)`

D

`Co_(2)(CO)_(8)`

Text Solution

Verified by Experts

The correct Answer is:
C
`CO` is an important ligand. It can donate an electron pair to many transition metals, forming carbonyl compounds. The number of `CO` molecules bonded to the metal is generally in accordance with the effective atomic number rule. Carbonyl formed with chromium is actually `Cr(CO)_(6)`.
