Initiation Cl. + C6H5CH3 yields C6H5CH2 + HCl Propagation C6H5CH2Cl termination Or just write curly arrow for direction for all electrons To break the Cl-Cl bond 8. Same empirical formula, differ by CH2 ethanoic acid is higher; larger mass, more intermolecular forces, larger surface area any OH located on a different carbon
