Benzene is less reactive than alkenes because it has a stable aromatic ring structure, which leads to a high degree of resonance stabilization. This stability reduces the tendency of benzene to undergo addition reactions that are commonly seen with alkenes. Additionally, the delocalization of electrons in the benzene ring provides extra stability, making it less likely to undergo reactions that would disrupt this resonance.

Is benzene less reactive towards electrophillic substitution reaction?
No, Haloarenes are less reactive than benzene towards electrophillic substitution reaction. This is because the halogen atom attached to benzene ring in haloarenesis slightly deactivating and orthoand para directing. so attack can only take place at orthoand para. Also the halogen atom in Haloarenesdue to its -I effect has some tendancyto withdraw electrons from the benzene ring and hence making it deactivating.Since the ring gets deactivated as compared to benzene, haloarenesare less reactive than benzene in electrophillicsubstituionreaction.
Why haloarenes are less reactive towards electrophile than benzene?
Haloarenes are less reactive towards electrophiles than benzene because the halogen substituents on the aromatic ring act as electron-withdrawing groups, reducing the electron density on the ring and making it less susceptible to attack by electrophiles. This results in a decreased reactivity towards electrophilic substitution reactions compared to benzene.
Why do 5-membered ring aromatic heterocycles pyrrole and furan undergo electrophilic substitution more rapidly than benzene while 6-membered ring heterocycles like pyridine are less reactive than Benz?
pyridine is less reactive than benzene because when we form its conjugate base then it'll b more stable than dat of benzene.. so more stabler means less reactive.......and also due to more resonance in benzene it will b more reactive...same 4 furan and pyrrole
Why nitration of nitrobenzene is difficult than nitration of benzene?
Nitration of nitrobenzene is more difficult because the nitro group is an electron-withdrawing group, making the nitrobenzene less reactive towards electrophilic aromatic substitution reactions. In contrast, benzene is more reactive because it does not have any electron-withdrawing groups attached to it.
What is the most substituted alkene and how does its reactivity compare to less substituted alkenes?
The most substituted alkene is typically more stable and less reactive than less substituted alkenes. This is because the increased number of alkyl groups attached to the double bond provides greater electron density, making the double bond less susceptible to attack by electrophiles.
Which is most reactive ethyne or benzene?
An alkene is more reactive than alkyne. as double bond can donate pair of electron. while in tripple bond the bond length is less than double bond. Alkkynes have more attractive forces than alkene. so alkene is more reactive.
Why is aspirin more reactive than benzene?
Benzene has a stable structure. Aspirin has an carboxylic group with delocalized electrons. So aspirin is more reactive than benzene.

Why does bromine react with hexene but not benzene?
Adding halogens to alkene groups (X2) requires that the product adopt an anti configuration. Hexene will also lose its double bond upon bromination. Benzene is energetically unfavorable when a reaction attempts to break its double bond. The resonance benzene has makes it very stable, and thus very hard to break.
Why haloarenes are less reactive towards electrophile than benzene?
Haloarenes are less reactive towards electrophiles than benzene because the halogen substituents on the aromatic ring act as electron-withdrawing groups, reducing the electron density on the ring and making it less susceptible to attack by electrophiles. This results in a decreased reactivity towards electrophilic substitution reactions compared to benzene.
Why the benzene ring is not much reactive as the pyrrole?
The benzene ring is less reactive than pyrrole because it is very stable due to its aromaticity. The delocalization of pi electrons in the benzene ring creates a high resonance energy, making it less inclined to undergo reactions. In contrast, pyrrole is more reactive because it is not fully aromatic and has more reactive sites available for bonding.

What is most reactive benzene or ethane.?
Benzene is generally more reactive than ethane due to its unique structure and the presence of a conjugated π-electron system. While ethane is a saturated hydrocarbon that primarily undergoes reactions such as combustion and substitution, benzene can participate in electrophilic aromatic substitution reactions due to its delocalized electrons. This makes benzene more susceptible to reactions with electrophiles. However, benzene's stability also means it is less reactive in some conditions compared to alkenes or alkynes.
Why nitration of nitrobenzene is difficult than nitration of benzene?
Nitration of nitrobenzene is more difficult because the nitro group is an electron-withdrawing group, making the nitrobenzene less reactive towards electrophilic aromatic substitution reactions. In contrast, benzene is more reactive because it does not have any electron-withdrawing groups attached to it.
What is the most substituted alkene and how does its reactivity compare to less substituted alkenes?
The most substituted alkene is typically more stable and less reactive than less substituted alkenes. This is because the increased number of alkyl groups attached to the double bond provides greater electron density, making the double bond less susceptible to attack by electrophiles.
Why is benzene less reactive than alkenes though it has three pi bonds?
It's because of resonance, which is the delocalization of electrons (the pi electrons). This delocalization lowers the potential energy of the benzene and thus renders in more stable.
Why is benzoyl chloride less reactive than ethanoyl chloride?
Remember that acid chlorides typically undergo nucleophilic substitution in which the partially positively charged carbon is attacked by nucleophile. Due to resonance(delocalization) in benzoyl chloride, the positive charge isn't concentrated in carbonyl C atom unlike in ethanoyl chloride but spreads over o and p positions in benzene ring. So, the carbonyl carbon in benzoyl chloride is less positive, less susceptible to nucleophilic attack and hence, less reactive.
