Does phenol react with acidic KMNO4 and why

React. Phenol is reductive and can be oxidized by oxygen in the air"P-benzoquinone", so the phenol mouth is placed in the air and becomes"Pink".That's why.

Potassium permanganate is more oxidizing than oxygen and can oxidize it.

When potassium permanganate oxidizes phenol, it can even see the luminescence phenomenon, which is chemically called"Luminescence chemical reactions".

Reactive phenol is reducible.

Without reaction, phenol is an acid weaker than carbonic acid, which can only be said to have strong oxidation with the addition of potassium permanganate.

Yes. Because phenol contains hydroxyl groups.

Acidic KMno4 has strong oxidizing properties.

Oxidizes hydroxyl groups.

Yes, high school chemistry textbooks say that phenol can be oxidized by oxygen in the air into a pink substance, and the oxidation of acidic KM4 is stronger than that of oxygen, so phenol can react with acidic KM4.

OK. Can be oxidized to pink p-benzoquinone.

The mechanism is the same as that of O2, which is due to the production of the original (O), which attacks the weak bond of phenol.

Rearrange or resonate the electron cloud (as it can be understood here) to produce more stable quinone aromatic compounds!

Yes, acidic kmno4. Good oxidation!! Phenol is susceptible to oxidation. Phenol is unstable.

Answer (1) When the homolog of benzene or the side chain of aromatic hydrocarbons is a hydrocarbon group, regardless of the number of carbon atoms lacking dust in the hydrocarbon group, as long as there are hydrogen atoms on the carbon atom directly connected to the benzene ring, it can be oxidized to a carboxyl group by the acidic KMNO4, and the carboxyl group is directly connected to the benzene ring. (2) Not all benzene congeners can.

Answer (1) When the homologues of benzene or aromatic hydrocarbons are hydrocarbon groups, regardless of the number of carbon atoms of the hydrocarbon group, as long as there are hydrogen atoms on the carbon atoms directly connected to the benzene ring, they can be oxidized to carboxyl groups by acidic KMNO4, and the carboxyl groups are directly connected to the benzene ring. Not all homologues that contain benzene can fade the acidic KMNO4 solution, and if not, the reason is that there are no hydrogen atoms on the carbon atoms directly attached to the benzene ring.

35 c6h5c2h5 + 54 kmno4 + 81 h2so4 → 27 k2so4 + 136 h2o + 40 c6h5cooh + 54 mnso4

The most important product is benzoic acid.

The product of xylene oxidation by acidic KMNO4 is benzalic acid.

The product of oxidation of benzene congeners by the acidic KMNO4, and the restriction that each side chain is oxidized to a carboxyl group is that there is at least one hydrogen atom on the carbon atom directly attached to the benzene ring.

Note: If there is no hydrogen atom on the carbon atom directly attached to the benzene ring, it remains unchanged.

Answer (1) When the homologues or aromatic hydrocarbon side chains of benzene are hydrocarbon groups, regardless of the number of carbon atoms of the crypto-burning hydrocarbon group, as long as there are hydrogen atoms on the carbon atoms directly connected to the benzene ring, they can be oxidized by acidic KMNO4 to be carried into carboxyl groups, and the carboxyl groups are directly connected to the benzene ring. Not all benzene congeners can make them acidic.
