Octane (C8H₁8) is a straight chain of carbon atoms with no dipole moment and a boiling point of 125°C. Water has a dipole moment, can hydrogen bond and has a boiling point of 100°C. The difference between these two boiling points can best be rationalized by: A. Intermolecular forces between molecules with dipole moments are greater than between molecules with no dipole moment B. Hydrogen bonding is a strong intermolecular force C. London dispersion forces are weak but there are many LDFs in octane so the net IMF in C8H₁8 is greater than the net IMF in H₂O D. London dispersion forces are strong and so the boiling point of octane is greater than the boiling point of water O A OB O C OD
