Intermolecular forces (IMPs) are the forces of attraction (or sometimes repulsion) that act between neighboring molecules All IMPs are based on etectrostatic interaction and are relatively weak compared to the Intramolecular forces that hold the atoms within a molecular together. In today, workshop you will practice to identify IMFs and predict their effect on boiling point melting point, vapor pressure and enthalpy of vaporisation (Delta Hvap). The Delta Hvap for a given molecule is the energy required to transform a...

Think about intermolecular forces and the stronger the intermolecular force the more energy needed to separate the molecules. Just thinking about this, put the properties below in the correct category. Hints: Vapor pressure is high if it is easy for molecules to escape from a liquid into the gas phase. High surface tension means the liquid molecules do not separate easily Viscosity is the "thickness" of a liquid substance Strong intermolecular forces Weak intermolecular forces Answer Bank high boiling point...
