Bond Length Order in Ni(CO)3PF3 and Ni(CO)3PMe3

Ni(CO)3PF3 and Ni(CO)3PMe3 are two different compounds that have different bond length orders. The bond length order in these compounds is determined by the nature of the ligand and the metal center. The following headings discuss the bond length order in Ni(CO)3PF3 and Ni(CO)3PMe3.

Bond Length Order in Ni(CO)3PF3

Ni(CO)3PF3 is a coordination compound that contains nickel, carbon monoxide, and phosphorus trifluoride. The bond length order in this compound is determined by the nature of the ligand and the metal center. The bond length order in Ni(CO)3PF3 is as follows:

1. The Ni-P bond length is the longest.
2. The Ni-F bond length is shorter than the Ni-P bond length.
3. The Ni-CO bond length is the shortest.

The reason for the bond length order in Ni(CO)3PF3 is due to the electronegativity difference between the ligands and the metal center. The phosphorus trifluoride has a higher electronegativity than the carbon monoxide, which makes the Ni-P bond longer than the Ni-CO bond.

Bond Length Order in Ni(CO)3PMe3

Ni(CO)3PMe3 is a coordination compound that contains nickel, carbon monoxide, and trimethylphosphine. The bond length order in this compound is determined by the nature of the ligand and the metal center. The bond length order in Ni(CO)3PMe3 is as follows:

1. The Ni-P bond length is the longest.
2. The Ni-CO bond length is shorter than the Ni-P bond length.
3. The Ni-Me bond length is the shortest.

The reason for the bond length order in Ni(CO)3PMe3 is due to the steric hindrance of the ligands. The trimethylphosphine ligand is larger than the carbon monoxide ligand, which makes the Ni-Me bond length shorter than the Ni-CO bond length.

Conclusion

In conclusion, the bond length order in Ni(CO)3PF3 and Ni(CO)3PMe3 is determined by the nature of the ligands and the metal center. The bond length order in Ni(CO)3PF3 is Ni-P > Ni-F > Ni-CO, while the bond length order in Ni(CO)3PMe3 is Ni-P > Ni-CO > Ni-Me. Factors such as electronegativity and steric hindrance play a role in determining the bond length order in these compounds.

Me gives +I effect nd F - I effect.. +I effect will increase electron density nd will favour back bonding of carboxyl complex with metal.. thus metal nd carbon will hv more bond order..nd c-o will hv less bond order.. thus, more bond lenght.. so ans is scnd one..
