molecule that is expected to have the lower vapor pressure is going to have the strongest intermolecular forces. 1473 This is what we call the Clausius-Clapeyron equation. In longer chain molecules, electrons more easily displaced than in compact molecules more polarizability n-pentane.1 C neopentane.5 C 18, summary Type of interaction Energy (kJ/mol) Interacting Species.

18 Summary Type of interaction Energy (kJ/mol) Interacting Species.
This is the summary Module for the chapter Liquids and Inte rmolecular Forces in the Brown.
Liquids are continuously vaporizing even if their not at their boiling point.
1118 The first type characteristics of literary essays analytical writing 7th grade of organic liquids I want to talk about are what we call aliphatic hydrocarbons. 0462 Therefore their bond with hydrogen will be the most polar. 1314 This molecule here that is branched has the weaker IMF and therefore the lower H of vaporization. 38 Sample Exercise.3 Calculating H for Temperature and Phase Changes Calculate the enthalpy change upon converting.00 mol of ice at 25 C to steam at 125 C under a constant pressure of 1 atm. 2006 That was our general chemistry lecture on intermolecular forces and liquids.
The higher the vapor pressure, the easier it goes from a liquid to a gas. In summary, intermolecular forces play a large role in many of the physical properties. 11.4 Properties of Liquids: Surface Tension and Viscosity.
