What are the disproportionation reactions of chlorine? What are the colours of the halogens in water and cyclohexane? How does chlorine react with water, cold alkali and hot alkali? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 2 – WCH12, but it can also be used for all UK exam boards. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides (which are best opened on Microsoft PowerPoint) is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – Useful generalisations for reactions between halogens and group 1 and 2 metals
Slide 4 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click
Slide 5 – 10: This section is about halogen displacement reactions. Students are shown the colours of the halogens in water and cyclohexane, an equation for an example reaction and the justification for using cyclohexane due to solubility and ambiguity
Slide 11 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click
Slides 12 -14: disproportionation reactions of chlorine with water, cold alkali and hot alkali, with mention of the usefulness of some of the products, e.g. sodium chlorate(V) in bleach
Slide 15 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click
Slides 16 – 18: Exam questions with mark scheme answers (included with the purchase of this resource)
