Marcus Rashford Brothers And Sisters, C) CO2 A molecules are hydrogen burning are hi Georgia bonding, hydrogen Other than the three types of intermolecular forces, there is another interaction that is very important for understanding the physical property of a compound, which is the ion-dipole force. Is 1 Pentanol a primary alcohol? The molecule with the lowest vapor pressure is the molecule with the strongest . Luis A. Camacho-Cruz, Emilio Bucio, in Green Sustainable Process for Chemical and Environmental Engineering and Science, 2020. But since hexane is a bigger molecule, I would expect it to have stonger intermolecular forces. . This order, as said before, is due to the interaction of oxygen with the surroundings, within the intermolecular forces we can find van der waals forces and hydrogen bonds, it is also know that H-bonds are stronger than van der waals forces so then that is why we have this type of interactions.
