In electrophilic aromatic substitution, the benzene ring acts as an electron donor (Lewis base or nucleophile) and reacts with an electron acceptor (Lewis acid or electrophile). The result of electrophilic aromatic substitution reactions is that an aromatic hydrogen is replaced by some other atom or functional group.
Naming benzene derivatives introduction. I mentioned in the last video that 99% of the aromatic compounds that you'll see in a chemistry or organic chemistry class is either going to be benzene or a molecule derived from benzene. So what I want to do in this video is just familiarize you with some of these molecules and how to name them.
