Which of the following is an incorrect description of benzene?
A) The CCC bond angles are all equal to 120°.
B) The molecule is planar.
C) The molecule is a 6-membered ring which contains alternating single and double carbon-carbon bonds.
D) The molecule is aromatic.
E) The molecule can be drawn as a resonance hybrid of two Kekule structures.

Question

Quizplus · Accepted Answer

Benzene is often represented as having alternating single and double bonds, but this is a simplification. In reality, benzene's structure is best described as a resonance hybrid of two or more Kekule structures, with delocalized electrons providing equal bond lengths and strengths between all carbon atoms, making the description of alternating single and double bonds incorrect.
