From Ochem Odyssey:
Which halogen has the most endothermic first propagation step during alkane halogenation?
A) Cl2
B) I2
C) Br2
D) F2
E) At2
Romano says that the answer is B and justifies his answer with the following halogen reactivity with alkanes:
F2 > Cl2 > Br2 > I2
He stops there.. not going on to include At2 and doesn't bother saying why. I can only assume that At2 should be next in this series but evidently not??
Anyone know what's going on here?
