WebThe correct answer is - There are '6' identical Cr - O bonds in the dichromate ion (Cr 2O 7−2). In a dichromate ion (Cr 2O 7−2)., there are 6 terminal Cr – O bonds. All these bonds are equivalent due to resonance. The Dichromate ions (Cr 2O 7−2). are oxoanions of chromium in the oxidation state +6. Hence option B is correct answer.
