Given that anisole (methoxybenzene) protonates primarily on oxygen in concentrated H2SO4, explain why 1,3,5- trimethoxybenzene protonates primarily on a carbon of the ring. As part of your reasoning, draw the structure of each conjugate acid.
Relationship G, G, and Q Reaction not at equilibrium, G = G + RTlnQ o R = gas constant (8.314 J/K x mol) o T = absolute temperature o Q = reaction quotient Ex: N 2 4g) 2NO (g) 2 2 Q= [NO ]2 [2 4 ] G reaction = nGproducts nGreactants = (2 mol)(51.3 kJ/mol) – (1 mol)(97.8 kJ/mol) = 4.8 kJ Relationship G and k Reaction at equilibrium: G = 0 and Q = k 0 = G + RTlnk or G = RTlnK or k = e G /RT lnk k At equilibrium Neg. pos. >1
