benzene - 2024 ACF Fall at Rutgers

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
