Which molecule/ion among the following cannot act as a ligand in complex compounds?

Options

  1. AC N -
  2. BC H 4
  3. CC O
  4. DB r -

Correct answer

B. C H 4

Step-by-step solution

For a molecule to act as a ligand, it should contain lone pair or negative charge. C H 4 does not have either a lone pair or π -electron pair it cannot act as ligand.
