When naphthalene undergoes an irreversible electrophilic aromatic substitution, the major product is the kinetic product, which proceeds through the most stable arenium ion intermediate. With this in mind, draw the curved arrow mechanism for the first step of the electrophilic aromatic substitution of naphthalene with l^+ generated from l_2 and CuCl_2. If you predicted the correct regiochemistry in the first step, then you can draw the curved arrows and a resonance structure in step 2 with an unbroken benzenoid ring....

Generally, any factor that stabilizes the sigma complex also stabilizes the transition-state leading to that complex. This effect leads to a lower transition-state energy and a faster reaction. rate-limiting transition state reactants + Br + FeBrz Η Br FeBr + O energy intermediate products Br + HBr + FeBr 3 -45 kJ/mol...
