29. Option C, regiochemistry which means that at which position reaction occurs to a particular group. EWGs gives meta reaction on benzene ring while EDGs gives o/p reactions.
30. Option E, Friedal-Crafts acylation/Alkylation. Especially AlCl3 is used as Lewis acid.
29. A blocking group can be used to control the outcome of an EAS? A) yield...
