Higher Chemistry Past Papers - Glow Blogs

1 Higher Chemistry past PapersSeptember 20201 About this study document has been designed to make revision and self-marking easy forstudents studying Higher Chemistry in those interested in how it was made, it has been compiled using information in this publication has been reproduced to support SQA qualifi-cations only on a noncommercial basis and can only be shared on that How to following two pages contain tables which cross-reference the course topicswith SQA question numbers for the years first table is for multiple choice questions; the second accesses Section2 questions.

2 Each question number is hyperlinked to the SQA question andclicking it will take you there. The question pages have further hyperlinks takingyou either back to the topic grid or to the SQA marking course, you can always just treat it as a succession of question Papers withmarking instructions. This will be useful for end-of-course timed Higher past Papers - Multiple Choice QsTopic20152016201720182019 Unit 1 Periodicity2, 34 StructureandBonding1, 4, 51, 2, 31, 3, 4,551, 2, 16 Oxidising and Re-ducing Agents2017, 18,191318, 193, 4 Unit 2 Systematic carbonchemistry15127, 107, 87, 9 Alcohols, , Esters, Fatsand Oils7, 8, 9,1478, 195 Soaps, Detergentsand Emulsions9, 10 Proteins8106 Oxidation of Food6, 10, 11126, 1126, 98, 11 Fragrances1351110 Skincare9 Unit 3 Controlling the rate1941, 2, 320, 22, 24 Getting the mostfrom reactants136.
