The bond length of C-=O bond in CO is 1....

The bond length of `C-=O` bond in CO is 1.20 Å and in `CO_2` it is 1.34 Å. Then C=Obond length in `CO_3^(2-)` will be

A

0.95 Å

B

1.36 Å

C

1.29 Å

D

1.25 Å

Text Solution

Verified by Experts

The correct Answer is:
C
In `CO_3^(2-)` due to resonance, C=O bond length is in between triple and double bond, ie, in between 1.2 and 1.34. Thus, answer is 1.29 Å.
