Mechanism Inspector: Investigate Organic Reaction Mechanisms


Organic Reaction Mechanisms is a core component of organic chemistry at 16 to 19 level. It is covered in A-levels, Scottish Highers and International Baccalaureate but also in all undergraduate chemistry courses.

Type of Activity

group work



Age Group

16 to 18 years

A series of resources linked through concept or context which can be used in whole or in part during teaching or learning


This site provides students of chemistry the opportunity to test themselves on their understanding by answering questions not only on the mechanisms themselves but on the underlying chemistry. It aims to:
1. help students to practice solving organic mechanism problems;
2. build confidence in core knowledge to help solve problems;
3. recognise evidence available to solve problems; and
4. challenge common misconceptions.
