Simple Organic Lab Work

I love organic chemistry but am well aware that this view of things is not held by all teachers and students! However, I feel I teach the subject well, but when it comes to lab work I do not do so well and this is something I need to work on. Today’s blog post aims to help me (and you) overcome this fear by giving you an idea for a simple lab to carry out (once you have the necessary reagents ...

Synthesis of Aspirin

Aspirin has been with us for long time - the first documented reports of its use occurred over 2000 years ago. That said, the aspirin may not be in the form that you instantly think of (ie, a tablet) but it has been used all the same. Aspirin is an analgesic, which means it has pain killing effects and it has been well documented that the ancient Egyptians used a special tea made out of willow bark to treat a number ...

Organic Chemistry – an introduction

Love it or hate it you won’t be able to ignore it – that’s organic chemistry. If this is a new topic to you, I hope that this blog posting will act as a ‘heads up’ something to help you to get ready for the course or to serve as a reminder / revision  of organic chemistry. I think it is important to stress that this is an introduction – the rules I write about below do get more complicated – ...

Dione (3)

C2O2, Ethene-1,-2-dione (or dicarbon dioxide) is our third and final example of 'dione'. Image uploaded and kindly reproduced according to the licence at: http://en.wikipedia.org/wiki/File:Dicarbon-dioxide-3D-balls.png The molecule is a hypothetical one, although recent research indicates that it may be temporarily formed before decomposing into two CO molecules (C2O2 --> 2CO) - however, it is estimated to exist for only 10-8 of a second.

Dione (2)

On Monday, I wrote about oxygen and Dione, a moon around Saturn. In my article I placed an image from Wikipedia. To fin this image, I search Wikipedia for 'Dione' and to my surprise, found that in Chemistry we have our very own Dione. In fact, to be more precise, we have two Dione's! Firstly: A diketone can also be called a 'dione' -  it is a ketone with two C=O groups. The following image is butan-2,3-dione, the simplest of all diones: This iage ...

How animals can predict earthquakes

For years it has been common for people to observe the strange behaviour of animals before an earthquake strikes but recently, scientists have begun to speculate exactly what does cause this phenomena to happen. And it seems that Chemistry may hold the answer .... ..... The current line of thinking is that chemical changes to ground water are the answer. It is thought that the extreme pressures that rocks undergo causes the formation of charge particles (ions) that make their way into ...

Focus on Carbon (2)

Todays YouTube clip follows on from yesterday. It sets the scene nicely for tomorroews clip but in terms of IB content doesn't really cover anything new. It does nicely deal with the formation of fossil fuels but as stated above, this does not rwally have much bearing on the IB couse. Stick with it though - it does get better!
