Which of the following has longest C-O bond length? `(Free C-O bond length in CO is 1.128 Å) `

A

`1.158Å`

B

`1.128Å`

C

`1.178Å`

D

`1.118Å`

Text Solution

Verified by Experts

The correct Answer is:
1
On account of synergic interaction between metal and CO bond order of CO reduces to approximately two half from three in carbonmonoxide. Thus bond length increases to `1.158Å`
