The second step of Experiment 5's multistep synthesis is an electrophilic aromatic substitution (EAS) reaction, similar to the r
eactions of our Klein text. What two key mechanistic steps are always involved in EAS reactions? A. Loss of a leaving group and proton transfer.
B. Nucleophilic attack and loss of a leaving group.
C. Nucleophilic attack and carbocation rearrangement.
D. Nucleophilic attack and proton transfer.
E. Loss of a leaving group and carbocation rearrangement.
