Video Lesson: Hydrocarbons - alkanes, alkenes and alkynes

Video Lesson

Subject
Chemistry

Description of the video lesson
In this video we look at three hydrocarbon molecules: alkanes, alkenes and alkynes. We see how they are named and we compare saturated and unsaturated molecules and their reactions.

Level of English
The level of English is more technical than basic English vocabulary.

Pre-requisites
Students should have foundation level chemistry and the English language skills to discuss atoms, molecules and bonding.

Language aims
Simple sentences are illustrated wherever possible with annotated diagrams.

Subject aims
The video introduces three families of hydrocarbons with the aim of comparing and contrasting their properties.

Students' Difficulties
Students often find the idea of bonding abstract and they find the number of different options for molecules difficult.

Students' Skills
Students should be able to describe the difference between saturated and unsaturated hydrocarbon molecules at a basic level.
