What are IUPAC nomenclature rules? How do you number the carbon chain if there are two functional groups? What is a homologous series? 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 1 – WCH11, 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 – Think-Pair-Share question: what is a homologous series?
Slide 4 – Answer to question
Slide 5 – Alkanes presented as the simplest homologous series
Slide 6 – Homologous series members differ by a CH2 group. A small class activity on this slide provides students with the opportunity to verify this statement. Assign each student a homologous series and let them research the different members of the group and verify that indeed each member differs by CH2. The students can present their findings to the class
Slide 7 – 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 8 – 13: All the functional groups which student will encounter in their A level studies and beyond are presented to them here. Print slides 9 – 10 for students Functional group definition is also given here
Slides 14 – 15: Nomenclature starts here with Mark Eats Peanut Butter to help students remember the first four prefixes of the code!
Slide 16 - 18 : the full code for the up to 10 carbon atoms is given here in table form. Print slides 17- 18 for students
Slide 19 – Explanation for how to code for the compound, i.e. prefixes for haloalkanes, suffixes for alkanes, etc.
Slide 20 - Example of the code being used to name simple compounds
Slide 21 – Information on how to number the carbon chain
Slide 22 - learning pit-stop to check students’ learning.
Slide 23 – how to code for branched chains. General formula for alkyls is also given here
Slide 24 – how and when to use hyphens and commas in IUPAC names
Slide 25 – Name the compound question for students (cold call)
Slide 26 - learning pit-stop to check students’ learning.
Slides 27 – 32: Students will be taught how to derive the name from the formula, with a plethora of worked examples
Slide 33 - learning pit-stop to check students’ learning.
Slides 34 – 36: Students will be taught how to derive the formula from the name, with a plethora of worked examples
