For question 2) Electrophiles for the electrophilic aromatic
substitution reactions have to be very strong to react with the
stable aromatic rings. A nitronium ion is needed for nitration of
aromatic rings. Complete the mechanism of the formation of the
nitronium ion from concentrated nitric acid in concentrated
sulfuric acid.

Consider the reactivity of phenol, bromobenzene, toluene, and nitrobenzene toward electrophilic aromatic substitution. 1.) The most reactive compound is (pick one: phenol, bromobenzene, toluene, and nitrobenzene) because the (pick one: electron donating or electron withdrawing) character of the (pick one: alcohol group, methyl group, bromine atom, or nitro group) increases the rate of the reaction. 2.) The least reactive compound is (pick one: phenol, bromobenzene, toluene, and nitrobenzene) because the (pick one: electron donating or electron withdrawing) character of the...
