- For the photochemical halogenation reaction below, draw both propagation steps and include the mechanism arrows for each step. H CH ot CH3 CI-CI MM hv of CH H-CI CH3 2nd attempt See Periodic Table See Hint Draw only radical electrons; do not add lone pair electrons. Note that arrows cannot meet in "space," and must end at either bonds or at atoms. 1 i Add the missing curved arrow notation to this propagation step. 20 H ن S F P H CI Br 品arrow_forwardThe radical below can be stabilized by resonance. 4th attempt Draw the resulting resonance structure.
