Multiple Choice

Are the methyl groups in xylene, C₆H₄(CH₃) ₂, included in the aromatic part of the molecular structure?

A) Yes, the aromatic bonding extends throughout the molecule.
B) Yes, but only when the resonance form with double bonds to the methyl groups exists.
C) No, only the carbons in the ring are involved in the aromatic system.
D) No, only the hydrogens in the ring are involved in the aromatic bonding.
E) No, only the carbon atoms in xylene are involved in aromatic bonding, not the hydrogens.
