15.2: Structure and Resonance Energy of Benzene: A First Look at ...
No single structure provides an accurate representation of benzene as it is a combination of two structurally and energetically equivalent resonance forms representing the continuous cyclic conjugation of the double bonds.
• Benzene is a planar, hexagonal cyclic hydrocarbon • The C–C–C bond angles are 120° = sp 2 hybridized • Each carbon possesses an unhybridized p-orbital, which makes

2024年11月19日 · The 139 pm bond length is roughly in between those of a C=C double bond (134 pm) and a C-C single (154 pm) which agrees with the benzene ring being a resonance hybrid made up of 1.5 C-C bonds. Each carbon in the benzene ring is sp 2 hybridized which makes all the C-C-C and H-C-C bond angles in benzene 120 o and makes the overall …
8.6: Resonance Structures - Chemistry LibreTexts
The benzene molecule (\(\ce{C6H6}\)) consists of a regular hexagon of carbon atoms, each of which is also bonded to a hydrogen atom. Use resonance structures to describe the bonding in benzene. Given: molecular formula and molecular geometry. Asked for: resonance structures
Resonance Structures - Resonance Effect & Explanation with …
The molecules of benzene have a cyclic structure consisting of alternating single and double bonds between adjacent carbon atoms. Each carbon atom is also bonded to one hydrogen atom. The two possible resonance structures of benzene are illustrated below.

2024年4月16日 · Resonance in Benzene In modern instrumental studies, it has been confirmed that benzene bonds are all of the same length, or approximately 1.40 pm. Exactly halfway between the lengths of a carbon-carbon single bond (1.46 pm) and carbon-carbon double bonds (1.34 pm), a picometer = 1 × 10 −12 meter.
A Short Note on Resonance Structures of Benzene - Unacademy
Benzene has two resonance structures that illustrate the bond locations. When benzene’s two contributing structures are compared, all single and double bonds are swapped. Bond lengths can be determined using a variety of techniques, including X-ray diffraction.
15.2 Structure and Stability of Benzene - Organic Chemistry
In resonance terms (Section 2.4 and Section 2.5), benzene is a hybrid of two equivalent forms. Neither form is correct by itself; the true structure of benzene is somewhere in between the two resonance forms but is impossible to draw with our usual conventions.
Benzene – Aromatic Structure and Stability - Chemistry Steps
The perfectly symmetrical structure of benzene, however, indicates that it exists as a resonance hybrid: The actual bond length (1.395 Å ) is the intermediate between the sp 2 – sp 2 single bonds (1.46 Å) and double bonds (1.33 Å).

Usually, derivatives of benzene (and phenyl groups, when the benzene ring is incorporated into a larger organic structure) are depicted with only one resonance contributor, and it is assumed that the reader understands that resonance hybridization is implied.
