The two resonance configuration is equally probable in benzene. i.e. all the c-c bonds have 50% probability of single bond and double bond. As a result all the bonds become equal.

Why benzene undergoes electrophilic substitution reaction whereas alkenes undergoes addition reaction?
The cation formed upon addition of an electrophile to benzene is highly stabilized by resonance,whereas the cation formed to an alkene is stabilized by hyperconjugation. The loss of a proton in benzene is favourable due to the restoration of the cyclic pi-system.
Why halobenzenes are less reactive towards nucleophilic substitution reaction?
i think the question is wrong.benzene doesn't respond nucleophilic substitution respond electrophilic substitution it is electrophilic then due to resonance there is a partial double bond between carbon of benzene and halogens.so halobenzenes are chemically inert towards electrophilic substitution.
Why phenol do not react with PCl5 under room temperature and pressure?
NO!! Oxygen-Carbon Bond in phenol has double bond character in it due to resonance, which is hard to break.
Why is phenylhydrazine a better neuclophile than aniline?
Yes, in phenyl hydrazine the electron pair on terminal nitrogen is always available for attack while in analine the electron pair of nitrogen is less available due to involvement in resonance process with benzene ring.
Why phenoxide ion is more reactive than phenol toward electrophilic subsititution reaction?
In the phenoxide ion the charge is delocalized by the resonance in the benzene ring. There is no such delocalization in the ethoxide ion.
Are all C-C bond distances the same in C6H6?
No, in benzene (C6H6), the C-C bond distances are not all the same. Benzene exhibits a hexagonal structure with alternating shorter and longer C-C bond lengths due to resonance delocalization of electrons in the π system.
Benzene is what kind of bond type?
Benzene contains delocalized pi bonds, making it an example of an aromatic compound with resonance structures. These resonance structures are due to the delocalization of pi electrons around the ring, resulting in a more stable molecule.

Why does AMINE group activate the benzene ring more than the hydroxyl group?
The amino group activates the benzene ring more than the hydroxyl group because it is electron-donating due to its lone pair of electrons. This lone pair can delocalize into the benzene ring through resonance, stabilizing the molecule. In comparison, the hydroxyl group is electron-withdrawing due to its electronegative oxygen atom, which deactivates the benzene ring through resonance.
Is chlorobenzene polar or non polar?
Chlorobenzene is considered nonpolar because the dipole moments of the C-Cl bond cancel each other out due to the symmetrical structure of the benzene ring.
Benzene behaves differently from a hydrocarbon which?
Benzene differs from typical hydrocarbons due to its aromatic structure, featuring a ring of delocalized electrons. This unique structure provides benzene with exceptional stability and unique chemical reactivity, making it a versatile building block in organic chemistry. Additionally, benzene displays resonance stabilization and follows different rules for bonding compared to aliphatic hydrocarbons.
Why acetone don't form resonance?
Acetone does not exhibit resonance because there is no conjugation between the carbonyl group and the adjacent CH3 groups. Resonance requires the presence of alternate double bond and single bond arrangements in a conjugated system, which is lacking in acetone due to the sp3 hybridization of the carbon atoms.

Which has high resonance energy 'naphthalene or Diphenylmethane'?
Naphthalene has higher resonance energy compared to diphenylmethane, as naphthalene has a more extensive delocalization of electrons due to its two benzene rings being fused together. Diphenylmethane, on the other hand, has less delocalization due to the presence of a saturated carbon in the molecule.
Why is benzene unsaturated give reasons?
The benzene molecule is unsaturated but the double bonds present inside the benzene ring are delocalized due to bond resonance (pi structure). This makes the double bonds of benzene much less reactive then more discreet double bonds (as in ethylene). This structure makes it behave more like a saturated compound, preferring substitution reactions over addition reactions. It is resistant to addition reactions across the double bond because such a reaction reduces the resonance stabilization energy. However, when reactions do occur, resonance stability is almost always re-established (Birch Reduction reactions are exceptions. See related link).
Why peptide bond is rigid and planar?
The peptide bond is rigid and planar because of the partial double-bond character resulting from resonance between the carbonyl oxygen and the amide nitrogen. This restricts rotation along the bond axis, maintaining a fixed planar conformation. The resonance structure creates a stable arrangement, as any rotation would disrupt the conjugation and lead to higher energy state.
