Oxidation number of ( Cr ) in ( [ Cr ( CO )₆ ] ) is

Options

  1. A+6
  2. B-6
  3. C+3
  4. D0

Correct answer

D. 0

Step-by-step solution

CO (carbonyl) is a neutral ligand. So, oxidation number of the metal is metal carbonyl compounds will be 0 (zero). ( [ 0 Cr ( CO )₆ ] : Hexacarbonyl chromium (0). )
