Read moreFree 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

Read moreBromination, Chlorination, and Halohydrin Formation from Alkenes Alkenes undergo halogenation when treated with Cl2, Br2 and (less commonly) I2 to give vicinal dihalides These reactions
