I am a GCSE and A-level Chemistry specialist teacher in a 14-18 school with 15 years teaching experience and several years research experience. I provide GCSE, AS and A2 Chemistry resources (mainly for the AQA specifications) to help students practice the concepts learned in lessons and I am a firm believer in 'Practice makes perfect'. I strive wherever possible to include the answers to the worksheets.

AQA GCE A level Chemistry Aromatic Chemistry Specification Teacher Support Pack

(0)
This resource is a complete pdf scheme of work for teaching the AQA Year 2 Aromatic Chemistry topic. It includes teacher notes sheets, student sheets, worksheets, starters, practice and exam-style questions, and an aromatic chemistry test. All answers are included. The topic starts with a student specification tick sheet to help students organise and revise the topic. The content includes the structure and bonding of benzene, looking at the evidence for the structure and bonding in terms of lack of addition reactions, x-ray crystallography and thermochemical evidence. There is an extensive section on naming aromatic compounds, which includes 3 worksheets and 2 lesson starters. There is also full coverage of electrophilic substitution with a range of practice questions, 6 exam-style questions and a comprehensive aromatic chemistry test. Please note that not all pages can be seen in the preview so I have provided one nomenclature worksheet and answers in .docx format to show the style of the whole support pack.
