This quiz consists of 10 Introduction to organic chemistry multiple choice questions for the AQA AS and A-Level Chemistry specification.

The questions are a similar style and level of difficulty to the multiple-choice questions you’ll be given in the AQA Chemistry exams.

Though they’re based on the AQA specification, they’re also appropriate for students studying other exam boards.

Some of these questions are straightforward, some of them are horrible. You need to know how to do all of them by the time the exams come around though, so if there’s anything you can’t do (even if it seems a bit weird) make sure you work backward from the answer and figure out why the answer is what it is. If you’re not confident with organic chemistry you should download my FREE introduction to organic chemistry workbook (available from my TES shop).
