Intermolecular forces (IMFs) can be used to predict relative boiling points. Intramolecular forces are responsible for many macroscopic properties such as electrical conductivity, hardness, and luster. Read the entire lab handout. Evaporation requires the breaking of all intermolecular forces. Which halide ions are […] propanoic acid intermolecular forces, The conformational equilibrium of 3-(dimethylazinoyl)propanoic acid (DMAPA, azinoyl = N(+)(O(-)) has a weak pH-dependence in D(2)O, with a slight preference for trans in alkaline solutions. These intermolecular forces, or IMFs, affect many physical properties including boiling point, solubility, viscosity, and surface tension. The ordering from lowest to highest boiling point is therefore C 2 H 6 < C 3 H 8 < C 4 H 10.
