Link: Compound Interest

‘Compound Interest’ is a blog by a graduate chemist & teacher in the UK that looks at the chemistry and chemical reactions we come across on a day-to-day basis. As well as highlighting these facets of chemistry, it is also the site’s objective to provide interesting & educational infographics on a variety of chemistry topics, both for use in the classroom and for more general consumption.

Back to basics with today’s graphic, with a look at the different ways compounds in organic chemistry can be represented. Obviously, if you're a chemist, these will all be second nature, but as was quite fairly pointed out with regards to the food chemistry graphics, if you’re not well versed in chemistry, all of those lines and letters might well be a bit perplexing. Here’s a brief explanation of what they mean.

The molecular formula of a compound gives the exact number of each different type of atom (i.e. type of element) present in one molecule of the compound. This is useful because it allows you to work out the molecular weight of the compound, but can also be restrictive...
