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
b. A hydrogen sulfide molecule has lone pairs of electrons
Explanation:
The presence of lone pairs indictates that the molecule will be polar unless its molecular geometry is linear or square planar. In the case of H2S, its shape is bent due to the lone pair and it is a slightly polar molecule.
The least electronegative elements in the center of lewis structures because an atom in the central position shares more of its electrons than does a terminal atom. Atoms with higher electronegative are generally more reluctant to share their electrons.
