In chromate CrO42 - and dichromate Cr2O72 - there are 4 and 8 Cr-O bonds are there as follows <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-iroouzpfmodf.png" /> Total number of Cr-O bond = 12.

Q. The sum of the total number of sigma bonds between chromium and oxygen atoms in chromate and dichromate ions is

In chromate $C r O_{4}^{2 -}$ and dichromate $C r_{2} O_{7}^{2 -}$ there are 4 and 8 $C r - O$ bonds are there as follows

Total number of Cr-O bond = 12.
