Oxidation number of \(\mathrm{Cr}\) in \(\left[\mathrm{Cr}(\mathrm{CO})_6\right]\) is
- A 6
- B -6
- C 3
- D 0
Answer & Solution
Correct Answer
(D) 0
Step-by-step Solution
Detailed explanation
CO (carbonyl) is a neutral ligand. So, oxidation number of the metal is metal carbonyl compounds will be 0 (zero). \(\left[\stackrel{0}{\mathrm{Cr}(\mathrm{CO})_6}\right] \text { : Hexacarbonyl chromium (0). }\)
