Web29. Activity 1. Strength of IMFA and Physical Properties of Covalent Compounds For each pair of molecules, identify the one with the higher boiling point (BP), melting point (MP). Viscosity (V), cartace tentoon (ST) and Vapor pressure (VP). Answer:boiling pointmelting pointviscositysurface tensionvapor pressure. Web14. When the attractive forces holding particles together are greater, you have to get to a higher temperature to break those forces, so the melting point is higher. 15. The strength of dispersion (London) forces tends to increase with increased molecular weight.
