Bromination of isobutane is a two‑step reaction. Step 1 reaction is: a coumpound with a central carbon atom with three single bonded C H 3 groups and one single bonded hydrogen plus radical bromine react to form a compound with a central carbon atom with a single electron and three single bonded C H 3 groups plus bromine with a single bonded hydrogen atom. Step 2 reaction is: a compound with a central carbon atom with a single electron and three single bonded C H 3 groups plus bromine single bonded to bromine react to form a coumpound with a central carbon atom with three single bonded C H 3 groups and one single bonded bromine plus radical bromine. The overall reaction is: a coumpound with a central carbon atom with three single bonded C H 3 groups and one single bonded hydrogen plus bromine single bonded to bromine react to form a coumpound with a central carbon atom with three single bonded C H 3 groups and one single bonded bromine plus bromine with a single bonded hydrogen atom. Using the table of bond dissociation energies for A−B⟶A+B, calculate the enthalpy of each step and the enthalpy of the overall reaction.
