There are 5 worksheets, 5 homework tasks, and an examination-style assessment test, each with answers included in this unit.
* These topics contain content suitable for separate Chemistry students only.
Cracking hydrocarbons and alkenes
Summary
Each topic is designed for teaching over roughly 1-2 lessons.
Crude oil continues to play a crucial role in our lives, and this unit illustrates some of the key properties and uses of its highly important and essential-to-life components. The unit emphasises and consolidates the understanding of the molecular form at the outset of this unit, as many students confuse terms like ‘atom’, ‘ion’ and ‘molecule’. Once the various properties of molecules are understood, the unit then applies this understanding within the context of the hydrocarbons present in crude oil.
The unit studies the composition of crude oil through to its separation into fractions, and thereafter into an individual study of the alkanes, as the starting point for gaining an understanding of the properties of molecules in an homologous series. The unit then moves onto the alkenes as a different homologous series from the alkanes, together with a consideration of the cracking process.
The complete series covers the AQA GCSE (9-1) Chemistry 8462 and combined science (Trilogy) 8464 specifications for Chemistry. Content relating to the separate Chemistry specification or Higher level material is indicated throughout for easy identification.

The units we have ordered are proving really useful and helpful with development of materials for new specs. The Maths for D&T have been particularly helpful.
