Problem: Which of the following compounds or ions exhibit resonance?a. O3 b. CNO-c. AsI3d. CO32-e. AsF3

FREE Expert Solution

a. O3 

O → Group 6A → 6 val. e- x 3

The electrons in the double bond (O=O) can move to the other O-O bond

O3 exhibits resonance.


b. CNO-

C → Group 4A → 4 val. e-

N → Group 5A → 5 val. e-

O → Group 6A → 6 val. e-

- charge → +1 electron

The electrons in the double bonds can move about while maintaining the overall charge of the ion equal to -1.

CNO- exhibits resonance.


c. AsI3

As → Group 5A → 5 val. e-

I → Group 7A → 7 val. e- x 3

ideal structure → no pi electrons that can move about

AsI3 do not exhibit resonance.


d. CO32-
