The reaction H2 + Br2 → 2HBr proceeds via which mechanism?(a) Free-r

1.	The reaction H2 + Br2 → 2HBr proceeds via which mechanism?(a) Free-radical(b) Ionic substitution(c) Elimination(d) PericyclicThe question was asked during an interview.My doubt stems from Non topic in division Rate Laws and Stoichiometry of Chemical Reaction Engineering
Answer» CORRECT OPTION is (a) Free-radical The explanation is: Bromine forms a free-radical and reacts with H2. Thus, free-radical mechanism is FOLLOWED. There is no elimination and no cyclic structure is formed as product or intermediate state.
