The bond angle in H2O is approximately 105° while the bond angle in H2S is approximately 90°. Which explanation best accounts for this difference?
a) H-S bonds are longer than H-O bonds.
b) S has d orbitals available for bonding, O does not.
c) H-S bonds are less polar than H-O bonds.
d) H-S bonds are weaker than H-O bonds.
e) O uses sp3 hybrid orbitals for bonding, S uses its 3p orbitals.
