Assertion: In `Cr_2O_7^(2-)` ion, all the `Cr-O` bond lengths are equa

1.	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 assertionC. If the assertion is true but reason is falseD. If assertion is false but reason is true.
Answer» Correct Answer - 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.
