The incorrect statement about carbonate CO 3 2 - ion is,
Options
- AIt has planar structure
- BIt has one coordinate bond
- CIt has three resonating structure
- DHydrolysis of CO 3 2 - ion gives basic solution
Correct answer
B. It has one coordinate bond
Step-by-step solution
Resonating structure of carbonate CO 3 2 - ion are In resonating structures bonds are not fixed and therefore, all bond lengths are equal. The hybridisation of central atom is sp 2 . Thus, there is no coordinate bond present in CO 3 2 - . Hence, the second statement is incorrect.
