Hi guys,
I thought it would be due to aromaticity breaking difficulty?

In the bromination reaction, why are the double bonds which are par t of the phenyl r ing not brominated?
A. We only added one equiv alent bromine.
B. T he phenyl r ing is aromatic and aromaticity is diffic ul t to break .
C. Because they are in a ring
D. Because they are too hindered

    I think you are right. The aromatic ring has extra stability due to resonance.

  • Chemistry Lab -

    Yes B. I presume that the attempted bromination was carried out under addition reaction conditons?
