What are IUPAC nomenclature rules? What is the difference between structural formula, skeletal formula, displayed formula, empirical formula and general formula? 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.
