Melting Point2.  Animation of breaking of intermolecular forces in acetic acid molecule at three different temperatures: low, moderate, highAcetic acid molecules move slowest at low temperature; occupy least volume; have all blue intermolecular forces Acetic acid molecules move faster at moderate temperature; occupy more volume; have some blue intermolecular forces brokenAcetic acid molecules move fastest at high temperature; occupy large volume; have no blue intermolecular forces-water molecules move faster since lighter-acetic acid molecules move slower since heavier

This 12-minute video lesson discusses acetic acid to acetyl chloride mechanism. They can be generalized to forming any acid halide from a carboxylic acid. [Organic Chemistry playlist: Lesson 69 of 73].
