Why benzene undergoes electrophilic substitution reaction whereas alkenes undergoes addition reaction?

∙ 13y ago
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.

∙ 14y agoBecause benzene does not have localized pi bond but has an electronic cloud which is responsible its aromatic character and stability, to retain its stability benzene undergoes substitution reactions rather than addition.

∙ 11y agoResonance structure of benzene shows that carbon-carbon bond in benzene is neither double bonded nor single bonded, but half way between them. So benzene undergoes substitution reactions.

Why is benzene undergoes electrophilic reaction rather then nucleophilic reaction?

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.
What kind of reaction occurs when Br and cyclohexene are mixed?
It's called an addition reaction. Specifically, it's an electrophilic addition reaction.
Why benzene undergo electrophilic substitution reaction easily and nucleophilic substution reaction with difficulty easily and?
the electron in benzene are delocalised making d ring to be elctron rich,thereby undergoing electrophilic substitution.benzene cannot undergo nucleophillic substitution,it can only undergo if it is substituted with an electron withdrawing group
Which compounds take part in an addition reaction?
Ethene undergoes addition reaction
What is electrophilic addition reaction?
The Electrophilic Addition Reaction is when the attacking species during the addition reaction is"Electrophile", it is called "electrophilic addition reaction". Examine: (+) (-) (+) (-) (+) (-) CH2Br-CH2BràH2C-CH2+BrBr-àH2C=CH2+Br2-

What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
electrophilic substitution. and UV light or heat is required to all the reaction to proceed

What type of reaction is Cyclohexene and Bromine?
Electrophilic addition. Forms 1,2,-dibromocyclohexane

Definition of electrophilic substitutionat school level?
When a positive ion (electrophile) attacks on a pi bond or partially negative carbon atom and replace H as a positive ion then it is electrophilic substitution reaction.
Methanol is a electrophilic or a nucleophilic?
It depends upon incoming reagent, if nucleophile attacks on methanol then it undergoes nucleophilic reaction and if electrophile attacks on methanol then it undergoes electrophilic reaction i.e Methanol reacts with both.... Student of A-level, XII, From Moro, SOMIA AKBAR MEMON
Why does chlorobenzene give ortho and para products during electrophilic substitution reaction?
As there is an availability of lone pair of electrons on chlorine, it directs the benzene ring towards electrophilic substitution at ortho and para positions.. When we will draw the resonating structures of chloro benzene,we will see that negative charge resides at orho and para positions..
