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.
An alkyl group is a saturated hydrocarbon. All bonds are single bonds between two carbons or a carbon and a hydrogen. These bonds are hard to break so alkyl groups are not very reactive. An alkene has a double bond between two carbon atoms. A double bond is not as strong as two single bonds so one of the bonds is easily broken and replaced with another molecule. Double bonds are also electron rich and can donate their electrons to other molecules. This makes an alkene more reactive.
Alkenes are more reactive as they are connected to each other by double bonds so having free electrons in outer shell.
In aromatic aldehyde C6H5- group decrease electrophlicity by resonance. Due to this reactivity will be decrease
The difference is the degree of unsaturation.
In alkene, there is a double bond between two carbons.
In alkynes, there is a triple bond between two carbon atoms.
alkenes are more reactive due to presence of pi bond which is a weaker bond and easily undergoes the addition reaction.
Benzene
benzene is more reactive
This is because chlorine is an electronegative group and is pulling electrons away from benzene. This makes the ring less reactive and more positive. Then when a positive electrophile tries to attach, the benzene does not want to react.
Yes, the dark stops the formation of a bromine radical
CH could represent the moleculaes H-C///C-H (Ethyne/Acetylene) Or Benzene , which is C6H6
Among the elements listed in the question, potassium, by a large margin, is most reactive.
rubidium
Ethyne is most reactive where as ethane is least.
ethyne
Benzene has a stable structure. Aspirin has an carboxylic group with delocalized electrons. So aspirin is more reactive than benzene.
This is because chlorine is an electronegative group and is pulling electrons away from benzene. This makes the ring less reactive and more positive. Then when a positive electrophile tries to attach, the benzene does not want to react.
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.
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
