Aromatic Chemistry AQA Specification Teacher Support Pack

Aromatic Chemistry AQA Specification Teacher Support Pack

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.

AS and Year 1 Free-radical substitution Mechanisms Revision - Lollipanisms (Lollipop Mechanisms)

AS and Year 1 Free-radical substitution Mechanisms Revision - Lollipanisms (Lollipop Mechanisms)

A revision activity for learning and practicing free-radical substitution reactions. The above resources are needed along with a set of lollipop sticks. The stickers document contains 3 halogens (fluorine, chlorine and bromine - labelled as A, B and C) and 10 alkanes/halogenoalkanes (labelled 1 to 10) for the halogen to react with. Each pair or group of students should have a set of lollipop sticks containing 9 sticks with halogens printed or written on them (3 of each halogen) and one each of the 10 alkanes/halogenoalkanes. The sticks could be colour coded by adding a stripe of colour or washi tape around the top edge for ease of seeing. Students pick one halogen and one alkane/halogenoalkane and write the full mechanism including the initiation, propagation and termination steps. The answers are provided on 8 answer sheets which are set up to be printed on sticky labels (4 per sheet) or directly onto card to be cut up into A6 size. The cards could be ring bound (30 cards in total) to give one complete set of answers (A1-A10, B1 -B10 and C1-C10). Students can self-assess their answers. All combinations of answers included.
