Edexcel International A Level Chemistry Core Practical 5 lesson investigating rates of hydrolysis of halogenoalkanes with exam questions. All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 AS level lesson for Edexcel International Unit 1 – WCH11, but it can also be used for Edexcel UK A level, since the practical is the same (Core Practical 4 in the UK A level)! All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question.

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 your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – recap quiz on key terms relating to organic chemistry of halogenoalkanes
Slide 4 – aim of practical is presented to students (To investigate the relative rates of hydrolysis of primary, secondary and tertiary halogenoalkanes and of chloro-, bromo- and iodoalkanes)
Slide 5 – equipment list
Slide 6 – control measures for safety
Slide 7: method for the practical
Slides 8 – 11: results tables. Print the hidden slides as two slides per page and trim for your students
