Question

Answer the following about electrophilic aromatic substitution, for 10 points each:
[10e] A common example of electrophilic aromatic substitution involves ethylating (“eth-ill-ate-ing”) this cyclic molecule with formula C6H6.
ANSWER: benzene
[10h] In EAS, electron donating groups, such as hydroxyls, serve as directors to these two sites on the ring. These two sites are on either side of the meta carbon.
ANSWER: ortho [or 2 position] AND para [or 4 position]
[10m] Hydroxyls are ortho and para directors because they can form these bonds, allowing resonance to occur. The double bond in an alkene consists of a sigma bond and one of these bonds.
ANSWER: pi bonds
