Potential energy 5. The following reaction coordinate diagrams both describe the first propagation step of a radical halogenation, i.e. radical abstraction of hydrogen atom from the alkane by a halogen radical. Circle the following correct bolded words. alkane less than 1 kcal difference in E 2 kcal Progress of the reaction keal 1⁰ 2⁰ 3⁰ Potential energy about 1.5 kcal difference in E₂ alkane Progress of the reaction b. Reaction coordinate diagram A is an exothermic/ endothermic reaction. 2 kcal 1° d. Reaction coordinate diagram B is an exothermic / endothermic reaction. 2° 2 kcal a. Reaction coordinate diagram A represents radical abstraction by a chlorine / bromine radical. e. Radical halogenation of alkanes with Cl₂ is more / less selective than halogenation with Br₂ 3° C. Reaction coordinate diagram B represents radical abstraction by a chlorine / bromine radical.
