Final answer:
Water, sulfur hexafluoride, and tin (IV) carbonate are not ionically bonded compounds. Option 1,2 and 4 are correct..
Step-by-step explanation:
The compounds that are not ionically bonded are water (H2O), sulfur hexafluoride (SF6), and tin (IV) carbonate (SnCO34-). The compounds AuCl₃ (gold(III) chloride), tin (IV) carbonate, and platinum (II) hydroxide are all ionically bonded, comprising metal atoms bonded to nonmetal ions or polyatomic ions.
Water is a molecular compound composed of covalently bonded hydrogen and oxygen atoms. Sulfur hexafluoride consists of covalent bonds between sulfur and fluorine atoms. Tin (IV) carbonate is a covalent compound composed of tin, carbon, and oxygen atoms.The other compounds mentioned, such as AuCl3, PH3, and platinum (II) hydroxide, involve ionic bonding where there is a transfer of electrons between atoms.
