Acyl Chlorides (scan for video preview)

Acyl chloride to carboxylic acid? Acyl chloride + alcohol? Acyl chloride + amine? Acyl chloride to amide? Acyl chloride functional group? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 13 A level lesson for Edexcel International Unit 4 – WCH14, 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 your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – introduction to carboxylic acid derivatives
Slides 4 – 5: this section focuses on acyl chlorides as carboxylic acid derivatives, and the IUPAC naming system for acyl chlorides
Slide 6 – explanation for the electron deficiency of the carbon atom in the acyl chloride functional group
Slides 7 – 8: use this section to teach students about the reaction of acyl chlorides with water. There is an example equation and consideration given to the misty fumes of hydrogen chloride that will also be formed
Slide 9 – use this slide to teach students about the reaction of acyl chlorides with alcohol, leading to the formation of esters
Slides 10 – 11: use this slide to teach students about the reaction of acyl chlorides with ammonia, leading to the formation of amides. Students are shown the amide functional group
Slides 12 – 14: use this slide to teach students about the reaction of acyl chlorides with amines. Students are first introduced to what amines are (since they will not learn this until later in Topic 19) and shown how N-substituted amides are formed from these reactions. You can also use this section to explain to students why tertiary amines do not react with acyl chlorides.
Slides 15 – 21: exam questions with mark scheme answers included with this resource
