Assertion: In `Cr_2O_7^(2-)` ion, all the `Cr-O` bond lengths are equal.
Reason: In `Cr_2O_7^(2-)` ion all the `O-Cr-O` bond angles are equal.

A

If both the assertion and reason are ture but the reason is a true explanation of the assertion.

B

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

C

If the assertion is true but reason is false

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D

Correct Assertion : Two `Cr - O` bonds have different bond lengths than the remaining six `Cr - O` bonds
Correct Reason : `O - Cr - O` bond in the middle is different from other `O - Cr - O` bond angles.
