I loved playing with Lego when I was a young boy and I don't think it is an over-statement to say that the love of building more complicated constructions from simple Lego building blocks led, at least in part, to me becoming an organic chemist!
It struck me, recently, that Lego minifigures could be used to help illustrate some of the key concepts in Isomers and Stereochemistry. This is a topic that causes great consternation for many new Organic Chemistry students. And so the Mariachi-mers were born!
I will be sharing content on Isomers and Stereochemistry, using the Mariachi-mers, in early 2019. For now, here is a flow-chart for deciding how to compounds are related, illustrated with Lego Mariachi-mers (and a few Lego Fairy Bat-mers) for analogy. The image is large, so click on it to expand.
