Question

The bonds present in the structure of dichromate ion are (A) four equivalent Cr-O bonds only (B) si equivalent Cr-O bonds and one O-O bond (C) six equivalent Cr-O bonds and one Cr-Cr bond (D) eight equivalent Cr-O bonds

In dichromate ion (Cr2O72-) two tetrahedral units are shared through an oxygen atom. The two CrO bonds which share an oxygen atom are longer than other six equivalent CrO bonds.

Q. The bonds present in the structure of dichromate ion are
