We’ve spent a lot of time in previous posts “building up” and drawing out the molecular orbitals for various species. In this post we’ll learn

A common problem students tell me is that they feel that they know the material, but when they write an exam, they don’t do well.

What’s organic chemistry, and how is it different from most classes you’ll encounter? In this post I share a few useful metaphors from commenters on

Nucleophiles and Electrophiles, Nucleophilicity and Electrophilicity All through the series on understanding where electrons are, and how they flow, we’ve been talking about how the
Read moreThe Three Classes of Nucleophiles
I know I’ve said this before, but a whole lot of organic chemistry can be boiled down to “nucleophile attacks electrophile“. A nucleophile is a
