What is the order of reactivity towards Sulphonation is c6h6 c6d6 c6t6?

(C) C6H6=C6D6=C6T6 (D)C6H6C-T > C-D > C-H.

Which of the following is the correct order of reactivity towards nitration?

– Hence, we can conclude that the correct option is (C), that is the correct order of rate of nitration of the given compounds is G > A > B = C = D > E > F.

Which of the following is the correct order of reactivity towards Sulphonation?

The correct order of reactivity is: Chlorobenzene < Benzene < Toluene < Methoxy benzene. Arrange the following: Benzene, toluene, methoxybenzene and chlorobenzene in the order of reactivity towards sulphonation with fuming sulphuric acid.

Which is correct order for the rate of Sulphonation of benzene?

The correct order of the rate of sulphonation of benzene is $ {K_{{C_6}{H_6}}} > {K_{{C_6}{D_6}}} > {K_{{C_6}{T_6}}} $ . Therefore, the correct answer is option A. Note : Sulphur trioxide is the electrophile here because it is a highly polar molecule with a fair amount of positive charge on sulphur.

Which of the following reaction of C6H6 are reversible?

Sulphonation of phenol is a reversible process.

In which electrophilic substitution reaction slow step is breaking of C H bond?

The second step of electrophilic aromatic substitution is deprotonation. This breaks C–H and forms C–C (π), restoring aromaticity. You may recall that this is strongly favored – the resonance energy of benzene is about 36 kcal/mol.

What is the correct order of nitration of the following compound?

G > B > C > D > A > F.

Why nitration of chlorobenzene is slower than benzene?

Since chloro is an electron-withdrawing substituent, chlorobenzene is less electron-rich than benzene. Therefore the nitration will be slower.

Is anisole meta directing?

Examples of meta– directors include nitriles, carbonyl compounds (such as aldehydes, ketones, and esters), sulfones, electron-deficient alkyl groups, nitro groups, and alkylammoniums. (Compare that to the case of anisole, above, where nitration resulted in a <5\% yield of the meta product. )

What happen when benzene is treated with concentrated h2 S o4?

Explanation: Benzene when treated with concentrated nitric acid and sulfuric acid at 330K temperature it forms nitrobenzene that is nitration occurs. The nitration of benzene starts with the activation of with sulfuric acid that is through the protonation of nitric acid by sulfuric acid.

Why is sulfonation reversible?

Sulfonation of benzene is a reversible reaction. Sulfur trioxide readily reacts with water to produce sulfuric acid and heat. Therefore, by adding heat to benzenesulfonic acid in diluted aqueous sulfuric acid the reaction is reversed.

What are the rates of nitration of C6H6 C6D6 and c6t6?

The rates of nitration of C6H6, C6D6 and C6T6 are the same. The rate determining step for nitration through Electrophilic Aromatic Substitution is the attack of the electrophile (NO2 (+)) on the aromatic substrate.

What is the Order of reactivity in nitration using isotopes?

Performing experiments with isotopes to study mechanism of a reaction is called primary isotope effect. You are mistaken here. The order of reactivity in nitration is. C6H6=C6D6=C6T6. Rate of reaction doesn’t depend upon the isotope we are using because loss of proton takes place through a fast reaction.

What is the rate determining step in nitration of benzene?

In nitration of benzene or C X 6 D X 6, the rate determining or slowest step is the formation of the nitronium ion N O X 2 X + and not the formation of sigma complex as in the other electrophilic aromatic substitutions, therefore the rate is unaffected by the leaving of a hydrogen or deuterium atom.
