The electronegativities of carbon and sulfur are almost the same. Both elements form covalently bonded compounds with hydrogen. Why is hydrogen sulfide a polar compound while methane is a nonpolar compound? a. Sulfur has a stronger attraction for electrons than does carbon
b. A hydrogen sulfide molecule has lone pairs of electrons
c. Sulfur forms ionic bonds with hydrogen while carbon forms covalent bonds
d. Sulfur ions are larger than carbon ions
