Is naphthalene more reactive than benzene towards electrophilic aromatic substitution reaction?

Naphthalene is more reactive towards electrophilic substitution reactions than benzene.

Why naphthalene is more reactive than benzene towards electrophilic substitution reaction?

Answer: So naphthalene is more reactive compared to single ringed benzene . Naphthalene has two aromatic rings, but only 10 pi electrons (rather than the twelve electrons that it would prefer). This means that naphthalene has less aromatic stability than two isolated benzene rings would have.

Which is more reactive than benzene towards electrophilic substitution reaction?

Phenol is more reactive than benzene towards electrophilic substitution reaction. The donation of the oxygen's lone pair into the ring system increases the electron density around the ring. That makes the ring much more reactive than it is in benzene. The intermediate carbocation is more resonance stabilized.

Is naphthalene more reactive than benzene?

Naphthalene is more reactive than benzene, both in substitution and addition reactions, and these reactions tend to proceed in a manner that maintains one intact benzene ring.

Which is most reactive towards electrophilic aromatic substitution reaction?

Hence, the electron density on benzene ring is maximum in aniline. Hence, aniline is the most reactive towards electrophilic aromatic substitution.

Electrophilic Aromatic Substitution Reactions Made Easy!

Which is the least reactive towards aromatic electrophilic substitution?

Benzenesulphonic acid is least reactive in an electrophilic aromatic substitution due to −M effect.

What is the order of reactivity of the following compounds in electrophilic substitution?

Based on the above explanation we conclude that the increasing order of reactivity of the following compounds towards aromatic electrophilic substitution reaction is: D < A < C < B. Therefore, the correct answer is option (B).

Which position of naphthalene is more susceptible towards electrophilic substitution reaction?

In the electrophilic substitution, position 1 in naphthalene is more reactive that the position 2 because the carbocation formed by the attack of electrophile at position 1 is more stable than position 2 because of the resonance since it has 4 contributing structures.

Which position of naphthalene is more reactive?

The alpha position is more prone to reaction position in naphthalene because the intermediate formed becomes more stable due to more diffusion of charges through the adjacent pie electrons. Thus resonance do have its role to play in reactivity of alpha position.

How many compounds are more reactive than benzene towards electrophilic aromatic substitution reaction napthalene anthracene Phenanthracene pyrrole?

Among the given compounds, only five compounds are more reactive than benzene towards electrophilic aromatic substitution reaction.

Which of the following species is less reactive than benzene towards electrophilic substitution reactions?

So, Nitrobenzene molecule is less reactive towards electrophilic aromatic substitution.

Why nitrobenzene is less reactive than benzene towards electrophilic substitution reaction?

Notice that nitrobenzene is less reactive than benzene because the nitro group is a deactivating substituent. Notice also that meta-substitution reactions on nitrobenzene are faster than para-substitution reactions because the nitro group is a meta-directing group.

Why chlorobenzene is less reactive than benzene towards electrophilic substitution reaction?

Chlorine is more electronegative than hydrogen. It draws electrons in the ring towards itself. So, it reduces the electron density of the aromatic ring of the ring. Hence, chlorobenzene is less reaction than benzene in electrophilic substitution reaction.

Which is more reactive benzene naphthalene or anthracene?

Although naphthalene, phenanthrene, and anthracene resemble benzene in many respects, they are more reactive than benzene in both substitution and addition reactions.

Is naphthalene more electron rich than benzene?

@satyamkumarjha Yes you are right, naphthalene has higher nucleophilicity as well as higher electrophilicity than benzene.

Why naphthalene is aromatic?

As we are getting a whole number from, 4nπ+2 formula for naphthalene, so naphthalene is aromatic. Therefore, the naphthalene is an aromatic compound according to Huckel's rule because it has 4nπ+2 delocalised electrons. Note: Pi bonds are known as delocalized bonds. Pi bonds cause the resonance.

Why benzene is more aromatic than naphthalene?

Answer: So naphthalene is more reactive compared to single ringed benzene . Naphthalene has two aromatic rings, but only 10 pi electrons (rather than the twelve electrons that it would prefer). This means that naphthalene has less aromatic stability than two isolated benzene rings would have.

Why does naphthalene undergo electrophilic substitution reaction at alpha position?

question. Electrophilic substitution reaction in naphthalene is quite similar to benzene reaction. The alpha position is more stabilized than the beta position. The carbocation formed at an alpha position after the attack of an electrophile is much more stabilized by its resonance than the second position.

Which is more aromatic naphthalene or anthracene?

There are three aromatic rings in Anthracene. Therefore the order of resonance energy as per the benzene ring in the decreasing order is : Benzene > Naphthalene > Phenanthrene > Anthracene.

Which compound has highest tendency of halogenation through aromatic electrophilic substitution?

In series of activating group OH comes first then OCH3, hence, phenol is most reactive towards electrophilic substitution reaction.

Does naphthalene undergo addition reactions?

Naphthalene also undergoes addition reactions more readily than benzene. It is reduced by sodium and amyl alcohol to tetra-hydronaphthalene, whereas benzene is unattacked by the reagent. The product tetralin is also obtained by the partial catalytic hydrogenation of naphthalene.

Which of the following will be most reactive towards nucleophilic substitution?

Solution : Order of reactivity of different halo compounds towards nucleophilic substitution reactions are : <br> allyl chloride gt vinyl chloride gt chlorobenzene. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

Which of the following options represents the correct order of reactivity of above given compounds towards electrophilic addition?

Therefore, the correct order of reactivity towards electrophilic substitution reaction is toluene > benzene > chlorobenzene > nitrobenzene. Hence, the correct option is (C).

What is the correct order of electrophilic substitution of following alkene?

So, the decreasing order of EA is: (II) - (alkene) > I - (alkyne) > III - (alkene with one EWG) > (IV) - (alkene with two EWGs).

Which is most reactive in electrophilic aromatic substitution Mcq?

The correct answer is Option B. Fuming sulphuric acid, H₂S₂O₇, can be thought of as a solution of SO₃ in sulphuric acid - and so is a much richer source of the SO₃.
