Answer 2

Answer:

Which of the following organometallic compound is σ and π bonded -

ANSWER

Option (C) is correct.

[Co(CO)5 NH 3 ] +2 is σ and π bonded.

In this organometallic compound,bond between cobalt and CO ligands have both σ and π character.σ- bond formation between metal and carbon of CO takes place by overlap of filled bonding π 2p of CO with an empty metal d- orbital.

The 2nd overlap takes place between metal d- orbital with an empty antibonding pi orbital of the CO resulting in additional π- bond between the metal and same CO molecule.
