When dealing with radical halogenation, why does the most stable intermediate compound have the fastest reaction rate? I would assume that this is because the more stable intermediates are formed more readily and more permanently, thus allowing the reaction to fully progress quicker than a reaction involving less stable intermediates that would be more difficult to keep around through the termination step. I was told that this was in the right direction, but incorrect. What am I missing?
