How can the rates of hydrolysis of halogenoalkanes be investigated? What is the trend in reactivity of primary secondary and tertiary halogenoalkanes and how does bond enthalpy explain this? 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 – A recap on the tests for halide irons, with the colours of the precipitates
Slides 4 – 5: Explanation of how hydrolysis with silver nitrate solution works with example chemical equations
Slide 6 – Expected result for the hydrolysis of halogenoalkanes with different halogens but the same structure
Slide 7 – Explanation for this result
Slide 8 - Expected result for the hydrolysis of halogenoalkanes with different structures but the same halogen. The explanation (which is covered in more detail in Unit 4) is on this slide
Slide 9 – 11: Core Practical 5: Investigation of the rates of hydrolysis of some halogenoalkanes. Answers to the analysis questions from the lab book animate on to the screen when you click
Slides 12 – 15: Exam questions with mark scheme answers (included with the purchase of this resource)

Learning outcomes:

Understand how to compare hydrolysis rates of haloalkanes
Describe and explain observed results based on bond strength
Distinguish SN1 and SN2 reaction pathways
Practice applying knowledge in Core Practical context

This lesson supports both practical skills and theoretical understanding—ideal for preparing students for assessed practical work and data interpretation questions.

Edexcel International A level Chemistry - lessons with questions and answers | Topic 10 | Organic Chemistry: Halogenoalkanes, Alcohols and Spectra

This bundle is comprised of 8 PowerPoint lessons covering Topic 10 – Organic Chemistry: Halogenoalkanes, Alcohols and Spectra for the Edexcel International A level Chemistry course. The PowerPoints are as follows: 1. Halogenoalkanes Introduction 2. Comparing the rates of hydrolysis reactions 3. Halogenoalkanes Reaction Mechanisms (Nucleophilic Substitution and Elimination) 4. Alcohols and some of their reactions (Combustion, Halogenation and Dehydration) 5. Oxidation of Alcohols 6. Purifying an Organic Liquid 7. Mass spectrometry of organic compounds 8. Infrared Spectroscopy Each lesson is exactly that . . . a lesson. There is a starter slide, lesson objectives slide, introduction of new knowledge slides, worked examples and then opportunities for students to try independent practice through mini plenary tasks comprised of several questions of graded difficulties. Questions are interspersed through the lessons at regular intervals and always have answers that animate on to the screen when you click. THESE ARE NOT THE INFORMATION ONLY TYPE SLIDES THAT SOME PEOPLE SELL, which are useless for delivering a lesson. We are a team of teachers, and these lessons have been made by actual Chemistry teachers who currently teach in secondary schools in England. We know exactly what you need, trust me. Almost every lesson has exam questions included as word documents which were made using Exam wizard. The mark scheme and examiner’s report is at the end of the exam question and the answers have been screen shotted and pasted into the PowerPoint at the end. All the slides in every lesson are fully animated and include answers to every mini plenary question and exam question. Other topics available for Pearson Edexcel International AS Level from Lifeboat Teachers: * Topic 1 – Formulae, Equations and Amounts of Substance * Topic 2 – Atomic Structure and the Periodic Table * Topic 3 – Bonding and Structure * Topic 4 – Introductory Organic Chemistry and Alkanes * Topic 5 – Alkenes * Topic 6 – Energetics * Topic 7 – Intermolecular Forces * Topic 8 – Redox Chemistry and Groups 1, 2 and 7 * Topic 9 – Introduction to Kinetics and Equilibria If you have a positive experience with the bundle, please leave a positive review! This really helps promote our store!
