iGCSE - Edexcel - Year 11 Organic Chemistry presentation with activities, links, videos, terrible memes, Pearson Edexcel Syllabus Statements and a step by step structured process. Feel free to chop it up and use it as you see fit. I’ve added in bits of info that’s not entirely needed in the syllabus but helps round it out. In the esters section is a bit about the Durian fruit, it’s topical as I work in Asia but you can do what you wish with that.
