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.
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 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
Is iodine reactive or nonreactive?
Halogination of iodine does not produce products since the transition state is too slow and requires too much energy. Nucleophilic substitution with I- ion produces products. So it depends on the reaction you are looking at.
Is boron reactive or non reactive?
reactive
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.

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.

Is indium reactive?
It is as reactive as indium. Just kidding, it is reactive. Hoe reactive, more reactive than silver, but not as reactive as tin.
Is Rubidium reactive or non reactive?
reactive
Is boron reactive or non reactive?
reactive
Is Boron non reactive or reactive?
reactive
Is caesium reactive or non reactive?
Caesium is an extremely reactive chemical element.
