Χημικές ιδιότητες αλκανίων Αλογόνωση μέσω ελευθέρων ριζών (φωτοχημική αλογόνωση) Why does Br 2 react slower than Cl 2 in the halogenation of CH 4? The Rate determining step in the halogenation of CH 4 is the attacking of Cl 2 on CH 4 molecules. Cl 2 is a stronger reducing agent than Br 2. Therefore it donates its electrons much faster than Br 2 to form a bond.
