Which of the following statements about intermolecular forces are true? Check ALL that apply. There are penalties for incorrect answers. Hydrogen bonding only occurs when a molecule contains a hydrogen atom bonded to O, N or F atoms. Both dispersion forces and dipole-dipole interactions contribute to the intermolecular forces between polar molecules. For alkane molecules with similar molar masses, branched molecules (spherical shape) will have stronger dispersion intermolecular forces compared to linear molecules (linear shaped). A hydrated K+ ion will be surrounded by water molecules with their hydrogen atoms directed towards the cation. The strength of dispersion forces between noble gases increases with the atomic mass of the atom.
