Recognising the Type of Reaction

Recognising the Type of Reaction

(0)
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.

Quick and short presentation on how to balance the manganate (vii) half equation, to save you time. I have now added the oxidation of ethanol by acidified potassium dichromate (VI) as another example.

Drag & Drop functional groups

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
Animated electrophilic substitution

Animated electrophilic substitution

(2)
Make things move in your class. A little starter illustrating the nitration of benzene. Just open the ‘electrophilic substitution , nitration of benzene copy.html’ file and it will run in your browser. You can zoom in or out using the browser controls. Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work. I have also included it as a movie format.
