How to Assign R and S Configurations Without a Molecular Model

Chiral centers come in two flavours - vanilla or chocolate chip... Just kidding! They come in R and S varieties. There's a three-step process for assigning the R or S, and one of the steps in putting the lowest priority group at the back, away from you. But what do you do when the lowest priority group isn't behaving and isn't already at the back? Read on and watch the video to find out two simple strategies that will rock your chiral world!

How to Draw Newman Projections

2

You probably don't want me designing your house. I can't look at floorplans and 'see' what the finished building will be like. Similarly, when it came to understanding molecules in 3D, I wasn't a natural. I particularly remember being bad at Newman projections! And yet, as a research organic chemist, my specialty was stereochemistry. How does that work?!

Carbocation Rearrangements – Explained!

How and why do carbocations rearrange? Professors love to torture, err.. I mean "test" students with exam questions that involve carbocation rearrangements. It can be confusing to know how to spot what will happen in these reactions, but there's some basic principles that will have you migrating the right hydrides and alkyl groups in no time!
