Boiling

This lesson will look at a Binary Boiling Point Diagram of a Liquid-Liquid Mixture. This diagram will show temperature, mole fraction of toluene and the mole fraction of benzene. This lesson will also look at a digram to explain how to solve for the amount of molecules.

This lesson will look at Interpreting Boiling points and will give an explanation of with a step by step look to better explain the concept.

In this video I discuss the trend in boiling points and solubilities of the carboxylic acids. These are explained in terms of hydrogen bonds and van der Waals forces.

This video was recorded to accompany my video on "Steam Distillation". It explains what is happening when water boils and when an immiscible mixture of water and phenylamine boils. It then goes on to demonstrate the use of ice to boil water in an enclosed space - providing a simplified explanation based on the combined gas equation. Your contributions to the explanation will be appreciated. Please add them in the space below.

This video reviews the three main types of intermolecular force by way of explaining the boiling points of aldehydes and ketones and their solubility in water. It looks at van der Waals forces, dipole-dipole forces and hydrogen bonding.

In this video I look at the setup for Steam Distillation and explain its use in purifying liquids by distilling them well below their boiling points. This is useful because some liquids (e.g. phenylamine) begin to decompose when heated to their boiling points. It is one in a series of short videos looking at the main organic practical techniques: heat & distill; reflux distillation; washing and drying in solvent extraction; recrystallisation and melting point determination; and others. Note that the video entitled " boiling water with ice" explains the physical chemistry aspects associated with steam distillation.

In this video lesson, Mr. Scullion demonstrates a small laboratory scale fractional distillation of crude oil which produces petrol, paraffin, diesel, fuel oil and bitumen.

This Chemistry lesson is titled Biggest Mistakes in Chemistry Boiling and Evaporation and will give a detailed explanation of the topic.

This video on alcohols looks at nomenclature, classification and isomerism. All 17 alcohol-isomers of C6H13OH are considered. At the end it also compares their boiling points
