WebCO is a well-known strong pi -accepting ligand in organometallic chemistry that will labilize in the cis position when adjacent to ligands due to steric and electronic effects. The system most often studied for the cis effect is an octahedral complex M (CO) 5X where X is the ligand that will labilize a CO ligand cis to it. WebCorrect option is C) Neutral ligand means ligand with no charge on it. Example: H 2O,NH 3,CO,C 2H 4... ONO − has charge on it,therefore it is not neutral ligand. Hence option C …
