4 C30H62 is a nonpolar compound that is a solid at room temperature. Water is highly hydrogen bonded but is a liquid because
A Water molecules are very light.
B Water molecules ionize easily.
C The 62 hydrogen atoms in C30H62 allow for many instantaneous dipoles.
D C30H62 is so large it cannot melt.
E C30H62 has a lower melting point if dissolved in nonpolar hexane.
