• B.
• Phenol is most easily nitrated.

Is toluene and phenol same?

is that phenol is (organic compound|uncountable) a caustic, poisonous, white crystalline compound, c6h5oh, derived from benzene and used in resins, plastics, and pharmaceuticals and in dilute form as a disinfectant and antiseptic; once called carbolic acid while toluene is (organic compound) a colourless, inflammable …

Which compound can be sulphonated easily?

Toluene is most readily sulphonated among these because methyl group is electron donating (+ I effect), activate benzene ring for electrophilic aromatic substitution.

Which is most readily nitrated phenol or aniline?

Answer: Aniline is more easily nitrated than phenol as the NH2 group is a stronger R showing group than OH.

How phenol is prepared from toluene?

First toluene is converted to benzoic acid(by KMnO4/OH-). Then it undergoes acid catalysed esterification to form phenyl benzoate. Then, on addition of NaOH(saponification), it gives phenol and sodium benzoate.

Is phenol more reactive than toluene?

Note that the methyl group in toluene increases electron density only by hyperconjugation and inductive effect. Resonance effects are generally far more superior to hyperconjugation. Hence, without doubt, phenol is more activated towards EAS as compared to toluene.

When phenol is nitrated by conc HNO3 and h2so4 the product is?

The reaction of conc.

Why benzene is more readily nitrated than nitrobenzene?

Because the benzene acts as a nucleophile in electrophilic aromatic substitution, substituents that make the benzene more electron-rich can accelerate the reaction. Phenol, C6H5OH, undergoes nitration a thousand times faster than benzene does. Nitrobenzene, C6H5NO2, undergoes the reaction millions of times more slowly.

Why toluene is easily sulphonated?

What is the product isomer of nitrobenzene after bromination?

Bromination of nitrobenzene requires strong heating and produces the meta-bromo isomer as the chief product. Some additional examples of product isomer distribution in other electrophilic substitutions are given in the table below.

What is the difference between hydroxy and Nitro substituents?

For example, a hydroxy or methoxy substituent increases the rate of electrophilic substitution about ten thousand fold, as illustrated by the case of anisole in the virtual demonstration (above). In contrast, a nitro substituent decreases the ring’s reactivity by roughly a million.

Is nitration reagent more reactive than halogenation reagent?

Also, as noted earlier, toluene undergoes nitration about 25 times faster than benzene, but chlorination of toluene is over 500 times faster than that of benzene. From this we may conclude that the nitration reagent is more reactive and less selective than the halogenation reagents. Both sulfonation and nitration yield water as a by-product.

What is the role of substitution isomers in the nitration reaction?

Clearly, the alkyl substituents activate the benzene ring in the nitration reaction, and the chlorine and ester substituents deactivate the ring. From rate data of this kind, it is a simple matter to calculate the proportions of the three substitution isomers.
