Question

what is the IUPAC formulas for these

1) chromic oxide

2) chromous oxide

3) chromic trioxide

4) chromate oxide

Answer #1

Chromium(III) oxide is the inorganic compound of the formula Cr2O3. It is one of principal oxides of chromium and is used as a pigment.

Chromium dioxide or chromium(IV) oxide is an inorganic compound with the formula CrO2.

Chromium trioxide is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name.

The chemical name for CrO4 is chromium 4 oxide.
