Boiling Points and Intermolecular Forces
Introduction:Intermolecular force is the force of hook and repulsion betwixt molecules. They argon much weaker than covalent bonds. When simmering a liquid to form a gas, the intermolecular forces argon broken not the covalent bonds. A molecular chemical compound that has strong London dispersion forces will also consume a higher boiling point since more naught is required to break the intermolecular bonds. London forces are immediately relative to the number of electrons in the compound. The main reason between boiling points and melting is dipole-dipole forces which are stronger than London dispersion forces. dipole antenna dipole forces occur between partial positive and veto charges of a polar molecule. The strength of the force depends on the preindication or the difference of electro negativity. The stronger the intermolecular force is the more get-up-and-go is required to boil the liquid.
In order to boil a liquid we must overcome the intermolecular forces present without forming pertly bonds.
Purpose:The purpose of this lab exercise to the test the theory and rules for London and dipole dipole forces.
Question:What is the trend in boiling points of the hydrogen compounds of elements in groups 14-17?
Hypothesis:a) Based upon my friendship about dipole-dipole and London forces, I can predict that the bombastic the molecules will have higher boiling points. London forces are present in all molecules and are directly proportional to the molecular size. Dipole-dipole interaction is the attraction between a partly negative portion of one molecule and a partially positive portion of a nearby molecule. Dipole-dipole interaction occurs in...If you take to get a full essay, order it on our website: Ordercustompaper.com
