Some answers I can remember:
-pH: 3.3 (I think), 13 or 12
-33% for % by mass
-100% atom economy - no waste, environmentally friendly
-similarities: both form alkybenzene
-differences: Friedel-Crafts reactions normally used acyl chloride or halogenoalkane, but this was an alkene group
-Kekule structure favours electrophilic addition reactions. The other one shows that benzene undergoes electrophilic substitution reactions preserving the ring, so it is more stable.
-Increasing pressure would increase both the rate and equilibrium yield
-Increasing temperature would decrease the equilibrium constant
-methanol for one of the reagent
aldehyde, conc. Sulfuric acid, acidified potassium dichromate
