Which of the following can be oxidised to alcohol by KMnO4?

Which of the following can be oxidized to alcohol by KMnO4?

Potassium permanganate (KMnO4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. Under controlled conditions, KMnO4 oxidizes primary alcohols to carboxylic acids very efficiently.

Which of the following can be oxidised by KMnO4?

Primary alcohols such as octan-1-ol can be oxidized efficiently by KMnO4, in the presence of basic copper salts. However, the product is predominantly octanoic acid, with only a small amount of aldehyde, resulting from overoxidation.

Which alkane is gets oxidized to alcohol by potassium permanganate?

Description: Treatment of an alkylbenzene with potassium permanganate results in oxidation to give the benzoic acid. Notes: The position directly adjacent to an aromatic group is called the “benzylic” position. The reaction only works if there is a hydrogen attached to the carbon.

INFORMATIVE:  How do you turn an alkyl halide into an alcohol?

Can KMnO4 oxidize a tertiary alcohol?

Yes, that’s right. Tertiary alcohols readily undergo elimination to yield alkenes, then the KMNO4 reacts with the alkene to give syn dihydroxylation.

Which compound Cannot be oxidised by KMnO4 in acidic medium?


Which of the following will not be oxidised by KMnO4?

Answer. The compound can’t be oxidized by the ozone(O3) is potassium permanganate(KMnO4). KmnO4 on separation converts into K+ and MnO4 -. Since Mn O4 exhibit the maximum valency and it is not only be oxidized.

What Colour is KMnO4?

Potassium permanganate appears as a purplish colored crystalline solid. Noncombustible but accelerates the burning of combustible material.

Is KMnO4 an acid or base?

Potassium permanganate is a strong oxidizing agent in acid medium, but is a weak oxidant in the neutral and alkaline medium.

What is the chemical name of KMnO4?

Potassium manganate(VII)

Which acid can Decolourise KMnO4?

Explanation: When citric acid is added to potassium permanganate solution, the purple solution loses its colour and becomes colourless.

What is the symbol of potassium permanganate?


Does KMnO4 react with alkanes?

When a purple solution of the oxidizing agent KMnO4 is added to an alkene, the alkene is oxidized to a diol and the KMnO4 is converted to brown MnO2. … Alkanes and aromatic compounds do not react with potassium permanganate.

Which alcohol can be oxidized to a ketone?

The oxidation of alcohols is an important reaction in organic chemistry. Primary alcohols can be oxidized to form aldehydes and carboxylic acids; secondary alcohols can be oxidized to give ketones. Tertiary alcohols, in contrast, cannot be oxidized without breaking the molecule’s C–C bonds.

INFORMATIVE:  What happens when isopropyl alcohol reacts with copper?

What type of alcohol is resistant to oxidation?

Tertiary alcohols (R3COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms.

Can 2 propanone be oxidized?

The oxidation of the simplest secondary alcohol, 2-propanol, yields propanone. Tertiary alcohols cannot be oxidized in this way because the carbon to which the hydroxyl group is attached does not have another hydrogen atom attached to it.
