Why haloaranes are much less reactive than haloalkanes towards nuclophillic substitution rxn?
Haloarenes are less reactive than haloalkanes towards nucleophilic substitution reactions because the aromaticity of the benzene ring in haloarenes provides extra stability to the molecule. This stability reduces the likelihood of breaking the aromaticity of the ring during the substitution reaction. In contrast, haloalkanes do not possess this extra stabilization, making them more prone to undergo nucleophilic substitution reactions.

What is the difference between primary haloalkane and secondary haloalkane?
In a primary haloalkane, the carbon involved in the halogen-carbon bond is bonded to one other carbon. In a secondary haloalkane, the carbon involved in the halogen-carbon bond is also bonded to two other carbons.
Why do alkyl halides undergo the nucleophlic subtitution reaction?
haloarenes are less reactive than haloalkanes because: 1. resonance effect more the resonatinsg structures,more the stability 2.difference in hybridisation of the C-X bond i.e.,in haloalkanes,the hybridisation is sp3 whereas in haloarenes it is sp2 hybridised.As sp2 is more electronegative therefore bond length is shorter and hence stronger. these are the major reasons.
Why the electrophilic substitution going to occur in furon thiophene and pyrole?
Electrophilic substitution occurs in furan, thiophene, and pyrrole because these compounds have a lone pair of electrons on the heteroatom (oxygen, sulfur, or nitrogen), making them nucleophilic and reactive towards electrophiles. The aromaticity of these compounds is also maintained during the substitution reaction, making them favorable candidates for electrophilic substitution.
Why is allyl chloride more reactive than 1-chloropropane towards nucleophilic substitution reaction?
Allyl chloride is more reactive because it has a more substituted double bond, making the carbon that undergoes substitution more electron-deficient due to the inductive effect of the chlorine atom. This increases the electrophilicity of the allyl position, leading to a faster nucleophilic substitution reaction compared to 1-chloropropane, which lacks this electron-withdrawing effect.
Why haloalkens are more reactive towards nucleophilic nucleophilic substitution reaction?
Haloalkenes are more reactive towards nucleophilic substitution reactions because the presence of the electron-withdrawing halogen creates partial positive charge on the carbon, making it more prone to attack by nucleophiles. Additionally, the double bond in haloalkenes provides a site for nucleophilic attack, increasing the rate of reaction.

What is different between electrophilic and nucleophilic substation?
Electrophilic reagents are chemical species which in the course of chemical reactions, acquire electrons or a share in electrons from other molecules or ions. Nucleophilic reagents do the opposite of electrophilic reagents.
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.

Are alcohols more reactive than ethers?
No, ethers are generally less reactive than alcohols. Alcohols have a hydroxyl group (-OH) that can participate in various chemical reactions such as oxidation, dehydration, and nucleophilic substitution. Ethers, on the other hand, lack such a reactive functional group and are generally more inert.
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.
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 is bromine selective?
Bromine is less reactive than chlorine (and much less so than fluorine) so it is selective when it comes to halogenation substitution reactions.
What is a chemical reaction in which an uncombined element replaces an element that is part of a compound?
This is known as a single displacement or substitution reaction. In this type of reaction, the more reactive element displaces the less reactive element from its compound, causing a rearrangement of atoms and the formation of a new compound.
