A complete, ready-to-teach lesson on intermolecular forces for Pearson Edexcel International A Level Chemistry, Unit 2 (WCH12). See how London forces, permanent dipole–dipole forces and hydrogen bonds arise, and use them to explain boiling temperatures.

Every diagram is redrawn as editable PowerPoint shapes and builds click by click, so you can talk through each stage. Detailed teacher notes on every slide mean it works for your own teaching, a cover lesson or a new colleague.

What’s included (27 slides):

• Learning objectives slide
• Watch it: 9 step-by-step diagram slides with click-by-click builds and a caption on each
• Try it: “Which boils higher?” activity table, with a separate answer slide
• Check it: 4 quick multiple-choice questions for mini-whiteboards, with answers and explanations
• Exam tip slide: where students most often lose marks
• 5 exam-style questions (11 marks), each followed by a full mark scheme with examiner notes
• Key fact plenary slide
• Teacher notes on every slide: starter, questions to ask at each click, common misconceptions, stretch and support, plenary and homework

By the end of the lesson, students can:

• Explain how London forces arise from instantaneous and induced dipoles
• Explain how the number of electrons and molecular shape affect London forces
• Describe permanent dipole–dipole forces and hydrogen bonds
• Use intermolecular forces to explain boiling temperatures and the density of ice
