Why is biphenyl more reactive than benzene?

In biphenyl, one phenyl group acts as electron donor, while other acts as electron acceptor. Thus, due to this reason, the phenyl ring is more reactive than benzene towards electrophilic substitution.

What is the correct order of reactivity towards electrophilic substitution?

Therefore, the correct order of reactivity towards electrophilic substitution is Phenol > benzene > chlorobenzene > benzoic acid.

Why is benzene more reactive to Electrophile?

Electrophilic because an electrophile, the propyl carbocation attacks the molecule (benzene). Anisole is more reactive than toluene as the OCH3 group donates electrons into the benzene ring by mesomeric effect.

Which phenyl ring of n Phenylbenzamide is more reactive in electrophilic aromatic substitution reactions?

The left handed phenyl ring is more activated than the right handed phenyl ring. Hence the electrophile would preferentially attack on the left handed phenyl ring.

Does phenyl exert effect?

Phenyl group is known to exert negative inductive effect, but each phenyl ring in biphenyl (C6​H5​−C6​H5​) is more reactive than benzene towards electrophilic substitution.

Which is more reactive in electrophilic substitution reaction benzene or chlorobenzene?

Chlorobenzene is less reactive than benzene towards electrophilic substitution reaction.

Which of the following is in correct order of decreasing reactivity towards electrophilic aromatic substitution?

Therefore, the correct order of reactivity towards electrophilic substitution reaction is toluene > benzene > chlorobenzene > nitrobenzene.

Why is ethyl benzene more reactive than benzene?

Ethylbenzene contains an alkyl substituent, and is slightly more reactive than benzene. Methylbenzoate has a carbonyl carbon atom bonded to the aromatic ring. As a result, its rate of bromination is significantly slower than that of benzene.

Why naphthalene is more reactive than benzene towards electrophilic substitution?

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 is Phenoxide ion more reactive than phenol towards electrophilic substitution reaction?

Why? Answer: Due to greater ability of ion (than OH group) to donate electrons to the benzene ring, phenoxide ion is more reactive than phenol towards electrophilic aromatic substitution reactions.
