WebJan 23, 2024 · The reason for the higher boiling points of the primary amines is that they can form hydrogen bonds with each other as well as van der Waals dispersion forces and dipole-dipole interactions. Hydrogen bonds can form between the lone pair on the very electronegative nitrogen atom and the slightly positive hydrogen atom in another molecule. WebJun 5, 2014 · Explanation: Molecules which are capable of hydrogen bonds have hydrogen atoms which are covalently bonded to highly electronegative elements (O, N, F). The presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as …

WebThe boiling point is said to be influenced by several parameters majorly, Pressure: The boiling point of the liquid may get deviated due to variation in pressure. If the atmospheric pressure is found to be less than one atmosphere, then the boiling point of that liquid may reduce below the normal boiling point.
