Benzene is stable towards oxidation of KMnO4 because it is a stable aromatic molecule. For an oxidation there would have to be a reaction, but since there is no reaction it is stable. Benzene is stable until there is a catalyst such as FeCl3, FeBr3, AlCl3, etc. This type of catalyst is used because it makes the bonding molecule more electrophilic and so it wants to attach to the electron-rich, also know as nucleophilic, benzene ring.

Benzene is stable towards KMnO4 oxidation because benzene is a highly conjugated aromatic compound with delocalized pi electrons. This stability results in benzene not readily reacting with strong oxidizing agents like KMnO4. Benzene's structural arrangement of alternating double bonds makes it resistant to oxidation reactions.

∙ 14y agoBenzene is a six carbon ring with one hydrogen attached to each carbon. The carbons all form a single bond (aka sigma bonds) with their hydrogen and they bond with each other in such a way that between two adjacent carbons there is a single bond and the entire ring also shares electrons (a continual ring-shaped pie bond). The rigidity these special bonds give creates benzene's stability.

Why benzene cannot decolourize KMnO4 while alkenes can decolorize?
Benzene cannot decolorize KMnO4 because it does not undergo addition reactions due to its stable aromatic structure. Alkenes, on the other hand, can decolorize KMnO4 because they can undergo addition reactions with KMnO4, breaking the double bond and forming a colorless product.
What is the oxidation number assigned to manganese in KMnO4?
The oxidation number of manganese (Mn) in KMnO4 is +7.
What isThe oxidation number of mn in kmno4?
The oxidation number of Mn in KMnO4 is +7. This is because oxygen (O) is typically assigned a -2 oxidation state, with the total oxidation state of the compound being 0. By following the rule that the sum of oxidation states in a compound is equal to the charge of the compound, we find that Mn is in the +7 oxidation state in KMnO4.
What is the oxidation numbers for KMnO4?
In KMnO4, the oxidation numbers are: K(+1), Mn(+7), and O(-2).
How do you convert but-2-ene to ethanoic acid?
Oxidation with acidic KMnO4 or Ozonolysis followed by oxidation
How do aldehyde's react?
aldehyde is less stable than benzene so it react readily toward kmno4
Why benzene cannot decolourize KMnO4 while alkenes can decolorize?
Benzene cannot decolorize KMnO4 because it does not undergo addition reactions due to its stable aromatic structure. Alkenes, on the other hand, can decolorize KMnO4 because they can undergo addition reactions with KMnO4, breaking the double bond and forming a colorless product.

What isThe oxidation number of mn in kmno4?
The oxidation number of Mn in KMnO4 is +7. This is because oxygen (O) is typically assigned a -2 oxidation state, with the total oxidation state of the compound being 0. By following the rule that the sum of oxidation states in a compound is equal to the charge of the compound, we find that Mn is in the +7 oxidation state in KMnO4.
What are the equations of hexane benzene and acetylene in the Baeyer's test?
Hexane and benzene do not react in the ignition test. Only acetylene does. Acetylene has a triple bond if equivalent amount of KMnO4 is used. The equation is HCCH + KMnO4 -> HC (OH) = CH(OH).

Is acidic or alkaline kmno4 needed for the oxidation of toluene?
Acidic conditions promote the oxidation of toluene by potassium permanganate.
Acidified potassium permanganate reaction with toluene equation?
The reaction between acidified potassium permanganate and toluene results in the oxidation of toluene to benzoic acid. The balanced chemical equation for this reaction is: C7H8 + 2KMnO4 + 8H2SO4 → 2MnSO4 + K2SO4 + 7H2O + 7H2O + C6H5CO2H
What is the oxidation number assigned to manganese in KMnO4?
The oxidation number of manganese (Mn) in KMnO4 is +7.
What is the oxidation numbers of manganese in MnO4 1-?
The oxidation number of manganese in MnO4 1- is +7. Each oxygen atom has an oxidation number of -2, and the overall charge of the ion is -1. Therefore, the oxidation number of manganese can be calculated as +7 to balance the charges.
