This sheet is intended to provide practice in identifying and naming functional groups in organic substances. This is an important skill that repeatedly comes up in exam papers. As a theme, natural dyestuffs found in plants are used. There are five examples over two pages.

Exam boards often take unknown substances and ask students to apply their understanding of chemistry to them. To provide practice answering this type of question, I am developing a series of worksheets with this type of question. The series is called Practicexamquest.

Simple, black and white.

A very little crossword puzzle about making salts

I have improved my video of this reaction mechanism.

Useful as a starter round the board. Drag the models next to the correct name. If it is correct it will stick, if not it won't. This tests understanding of functional groups and different types of molecular model. Double click on the FuncDragAndDrop.html file, and you're there

One of the most useful skills in answering many GCSE chemistry questions is to work out what type of reaction is involved in the question. This helps you work out what the products may be, but also answer other questions about the reaction. Students often find this very difficult, mainly due to a lack of practice and experience. This simple information sheet with questions at the back is in black and white so can be readily photocopied.

In colour. Helps students interpret proton NMR spectra

Simple animated cartoon, with narration.

A simple worksheet in black and white for ready photocopying. Two sides, with a summary on the front and some questions on the back.

Reinforces understanding of this important mechanism. Sixth formers LOVE to cut & stick.

This is a simple powerpoint giving names and formulae of ions. Knowledge of these can provide a key to understanding chemistry at GCSE and A level. Print these off, laminate them, and display in a prominent position in a lab. (NB I have corrected the ammonium ion error)

A simple worksheet. Explanation on page one, standard electrode potentials on page 2, and a few questions on page 3.

This is a simple book of simple Sudoku puzzles. There are ten puzzles in total. The first five use the characters 1 to 9. The second five use the characters 1 to 9 and A to G. Solutions are provided.

This is a variation of my ‘drag and drop functional group’ activity. In this case you drag the structural formula to the correct name of the functional group. If it is correct it will stick, otherwise it won’t. Could be used around the whiteboard as a quick AFL. This is a simple html5 document- simply double click on the html file and it will load in your web browser.

I made a crazy cartoon illustrating the calculation of the enthalpy change from bond enthalpies for the reaction between chlorine and hydrogen. Just for fun really. Note: the youtube version is free.

A minute video giving defintions of nucleophile and electrophile. Because I could.
