Covalent bonding

I have made a cartoon of dot cross type diagrams for all of the structures on the AQA specification. Simple double click on the covalent bonding.html file and it runs in your browser. Its nice and colourful, big and bold (zoom in with your browser to make it as big as possible). Could use around the whiteboard, or for independent study at a computer. It’s not intended as a whole lesson, but as a useful resource that can be revisited a number of times with a class to reinforce what they need to know for the exam. Could be starter or plenary or interlude. Please note: in order to provide a rich interactive experience, my drag & drop 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.

This maybe helpful as a small revision exercise. Has a ‘check my answers’, ‘solve’, and ‘hint’ button. This runs in your browser.

A simple information sheet, with the emphasis on clarity. It may be useful to someone, somewhere.

One of my wacky videos illustrating the difference in reactivity of benzene vs phenol in terms of polarising power.

Graph of boiling points of hydrides.

The traditional textbook graph of this data is very confused. I feel that my presentation of the data emphasizes the role played by hydrogen bonding more clearly. The influence of atomic size on boiling point is also clearly shown by the bp of the noble gases.

A very simple worksheet to aid the distinction of addition polymers from condensation polymers. Explanation on page 1, questions on page 2.
