Which compound contains a longer C-C bond benzene or ethene?
c-c bond length in benzene is 1.397 angston and that of ethene is 1.34 angston structure of benzene is a resonance hybrid, therefore all the c-c bond lengths are equal but different from those in alkanes,alkenes, and alkynes.
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.
Do alkenes show mesomerism?
Yes, alkenes can exhibit mesomerism due to the presence of π electrons in the double bond, allowing for resonance stabilization. This can lead to delocalization of electrons along the pi bond, resulting in different resonance structures with varying bond orders.
What is the length of carbon bonds in benzene?
The carbon-carbon bonds in benzene are all the same length, approximately 1.39 angstroms. This is shorter than a typical carbon-carbon single bond due to the delocalized pi-electron cloud in the benzene ring structure.

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.
Why single and double bond length are same in benzene?
In reality, benzene does not contain alternating single and double bonds. It is more accurate to say that each carbon-carbon bond is in an intermediate state between a single and a double bond. Benzene therefore displays a property known as resonance.
Benzene is what kind of bond type?
Benzene has covalent bonds. Each of the six carbons in benzene is sp2 hybridized meaning the ring has both sigma bonds and pi bonds. Benzene is aromatic meaning its pi electrons are delocalized and form a pi system.
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 c c bonds in benzene are intermediate in length between single and double c c bonds?
Because in benzene molecule the pi electrons are delocalized (continuously changing their position within the hexagonal ring), so there are no fixed single and double bonds but are in mid of single and double bond character.
What type of hybridisation in benzene?
Benzene exhibits sp2 hybridization. In benzene, each carbon atom forms three sigma bonds with other carbons and hydrogens, along with one pi bond due to π overlap of p orbitals. This results in a planar structure with 120° bond angles between carbon atoms.
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 does OH and OR group activate the benzene ring?
The OH and OR groups are electron-donating groups that can donate electron density to the benzene ring through resonance, making it more electron-rich and activating it towards electrophilic aromatic substitution reactions. This is due to the ability of the oxygen atom in these groups to stabilize the positive charge in the resonance structures of the benzene ring.
Is chlorobenzene polar or non polar?
Biphenyl has equal charges on both benzene rings, this material is non polar
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.
Why are the bond lengths in no3- all identical and shorter than a nitrogen-oxygen single bond?
NO3- has three resonance structure. One double bond between N and O and another two N - O single bond. Since the double bond can be formed between N and any other O it is said that it has a resonance structure. This means that the true structure of NO3- is not any of this structure, but rather a hybrid of all three. Hence all 3 bond lengths would be identical AND shorter than single bond as it is basically an average between single and double bond. It is of course longer than a double bond
