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.

CCC Bond Angles

CCC bond angles refer to the geometric angles between three carbon atoms in a molecular structure, important in determining the shape and properties of molecules.

Resonance Hybrid

A composite representation of a molecule that cannot be depicted accurately by a single structural formula, illustrating electron delocalization.

Aromatic

Describes organic compounds that contain one or more planar rings of atoms with delocalized pi electrons, following Huckel's rule.

  • Absorb the defining structural features that segregate cyclic hydrocarbons into aromatic, antiaromatic, or nonaromatic classifications.
  • Comprehend the concept of aromaticity and its criteria, including Hückel's rule.

Final Answer :
C
Explanation :
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.
