Answer Key To Vapor Pressure Curves - yearbook2017.psg.fr Choose the molecule or compound that exhibits dipole-dipole forces as its strongest intermolecular force. Hydrogen bonds form when you have a negative O, N, or F atom in one molecule and a positive H atom attached to an O, N, or F atom in another molecule. The higher the molecular weight, the stronger the London dispersion forces. H-F bonds it can interact with itself and with other choh molecules. Hydrogen bonding occurs for molecules that has Hydrogen atom bonded to an electronegative atom like Oxygen. The energy required to break molecules apart is much smaller than a typical bond-energy, but intermolecular forces play important roles in determining the properties of a substance. Chegg HlSK0W~FX+ A$CwaugM]4kPu-A@/NPiNCZp89\o:[xxT\pyM3HoQKHDunQwH: 0lAE$8lnRTFDb The only forces left to consider are London dispersion forces.
