VSEPR & Shapes of Molecules

One for the chemistry students (and teachers!) out there today, with a look at how we can work out the shapes of some simple molecules using Valence Shell Electron Pair Repulsion (VSEPR) theory. These shapes are decided by the arrangement of electrons around the central atom in the molecule.

A Brief Summary of Inhalational Anaesthetics

If you’ve ever needed a tooth out, or had surgery of any kind, chances are you’ll have experienced use of an inhalational anaesthetic. All of the compounds shown above can induce general anaesthesia, and a range have been utilised since the initial discovery of nitrous oxide in the mid-1800s. Often, intravenous drugs will be used for induction […]

The Chemistry of the Odour of Decomposition

Continuing this week’s Halloween theme, today we’re looking at death – more specifically, the chemical agents behind the smell of it. Decomposition is an incredibly complicated process, but we do know a little about the chemical culprits behind some of the terrible smells as the body breaks down – so, what compounds are the must-haves […]

National Chemistry Week: The Chemistry of Candy

It’s currently National Chemistry Week in the US (apparently, we only get National Chemistry Week once every two years here in the UK), and the theme for this year is ‘The Sweet Side of Chemistry’. This seemed like as good an opportunity as any to look at some confectionary chemistry! In this graphic, we look at […]
