All the A level chemistry definition notes are in this document

All the A level chemistry definition notes are in this document

It consists most of the common mistakes you would make for all the topics in A level chemistry, as well as some additional knowledge (in the boundary of the A level syllabus, so the teacher may not tell you but it could come up in exam) to let you comprehend those concepts. You don't have to read the text book anymore if you have this note

It has everything you need to memorise about inorganic reactions, including reactions between water and silicon chloride.

Colour of most of the solutions, including complex ions

Rules to name complex ion

All the organic reactions you need to need to know in AS Chemistry, recommended for year 12

Includes all the aliphatic reactions you need to know in the A level syllabus, including conditions and relevant observation. I can guarantee that you could get 50% of the marks in Wjec chemistry paper 2 if you study this ;)

Rules when naming aromatic hydrocarbons (Just in A level syllabus)

Includes all the reactions you need to know about aromaticity such as Freidal-crafts alkylation and coupling reaction. You don't have to read all the context in the book to memories those reaction, this note has already did that for you :)

Includes everything you need to know about aromatic hydrocarbons , as well as most of questions about aromaticity such as evidence of the delocalised bonding model of benzene.

List of most common fragments that would appear in exam, after reciting this you don't have to think what fragment ion corresponds to the mass number.
