Which molecule, H2S or H2Se, is more polar and why, chemistry homework help
Which molecule, H2S or H2Se, is more polar and why?
A. H2Se is more polar than H2S because H2Se has greater dipole-dipole forces than H2S since the H-Se bond is more polar than the H-S bond.
B. H2S is more polar than H2Se because H2S has greater dipole-dipole forces than H2Se, since H2S has two lone pairs of electrons and H2Se does not.
C. H2S is more polar than H2Se because H2S has greater dipole-dipole forces than H2Se since the H-S bond is more polar than the H-Se bond.
D. H2Se is more polar than H2S because H2Se has greater dipole-dipole forces than H2S, since H2Se has two lone pairs of electrons and H2S does not.
E. H2Se is more polar than H2S because H2Se has a higher molecular mass than H2S, and molecular mass is the most important factor in determining polarities of molecules.
