The heavier halogens (Cl, Br, and I) form compounds in which the central halogen atom, X, is bonded directly to oxygen and to fluorine. Several examples are known, including those with formulas of the type FXO₂, FXO₃, and F₃XO. The structures of these molecules are all consistent with the VSEPR model. Draw Lewis structures and predict the geometries of 

(a) chloryl fluoride, FClO₂; 

(b) perchloryl fluoride, FClO₃;

(c) F₃ClO.
