Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. I’m not sure how to get the correct answer for this question. Hydrogen sulfide is non-polar on account of its nonpolar H–S bonds. NOCl is a polar molecule because the central nitrogen atom in the structure of NOCl has a lone pair of electrons present on it, which results in electron-electron repulsion. For example water (H20) is a polar bond. both c and f bonds on same side molecule is polar . Answer: SiF4 is a nonpolar molecule because the fluorine's are arranged around the central silicon atom in a tetrahedral molecule with all of the regions of negative charge cancelling each other out. Though it contains polar bonds (between the S and each O), these dipoles cancel out due to its structure, and the molecule itself has no net dipole. Solubility.
