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...

Which of the following statements are true about the deactivating nitroso substituent in electrophilic aroman -N=0 The nitroso group is predicted to be an ortho/para-directing group. Resonance withdrawing effects can explain why the nitroso group is deactivating. The nitroso group is predicted to be an meta-directing group. Inductive withdrawing effects can explain why the nitroso group is deactivating.
