Assertion : Carbon-oxygen bonds are of e...

Assertion : Carbon-oxygen bonds are of equal length in carbonate ion.
Reason : Bond length decreases with the multiplicity of bond between two atoms.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true and the reason is not the correct explanation of the assertion.

C

If assertion is true of the reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
B
`CO_(3)^(2-)` shows resonance and thus all the three bonds are of indentical bond length.
`O=underset(O_(-))underset(|)(C)-O^(-)harrO^(-)-underset(O_(-))underset(|)(C)=O harrO^(-) - underset(O)underset(||)(C)-O^(-)`
