Electrophilic Aromatic Substitution: Introduction
The Six Key Electrophilic Aromatic Substitution Reactions A key reaction of aromatic compounds is electrophilic aromatic substitution, where a C-H bond is broken and a

Free Radical Reactions – Chlorination of Methane Alkanes are pretty boring, chemically speaking. They don’t tend to undergo many reactions. However, when they are treated

Free Radical Chlorination: Selectivity This post is all about the selectivity of free-radical halogenation: what does “selectivity” mean, anyway? And how do we calculate it? It’s often

Last time we discussed the similarities (and differences) between the carbocation pathway for alkenes and alkynes. In this post, we’ll do the same for the

How does bromination of alkenes work? In the previous post we showed how the mechanism for bromination of alkenes can’t possibly go through a carbocation
