Answer 1

Answer #1

If electron donating groups on the benzene ring, bromination takes place on ortho and para positions.

If electron withdrawing groups on the benzene ring, bromination takes place on meta positions.

Aromatic heterocycles also undergo electrophilic aromatic substitution reactions. When furan is treated with an electrophile, the electrophile is installed only at the C-2 position. Explain why this reaction occurs only at the C-2 position, rather than the C-3 positions.(explain in words and resonance structures) Question 2 (10 pts).
