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.

∙ 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?
KMnO4 will add across the double bond of alkenes (or alkynes) resulting in the docolouring of KMnO4 but not an alkane such as ethane.
What isThe oxidation number of mn in kmno4?
+7.
How do you convert but-2-ene to ethanoic acid?
Oxidation with acidic KMnO4 or Ozonolysis followed by oxidation
Acidified potassium permanganate reaction with toluene equation?
toluene is benzene with CH3 reacting this with KMnO4 in acidic solution will produce a benzene with a carboxylic acid (CH3 will be oxidized)
What is the oxidation number assigned to manganese in KMnO4?
Manganese oxidation state = +7 So, it is also called Manganate(VII)
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?
KMnO4 will add across the double bond of alkenes (or alkynes) resulting in the docolouring of KMnO4 but not an alkane such as ethane.
Equation for benzene plus KMnO4?
no reaction takes place
Rank these items in order of increasing oxidation number for manganese Mn KMnO4 MnO2?
MnO2: oxidation number +4KMnO4: oxidation number +7
What isThe oxidation number of mn in kmno4?
+7.
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).
How do you convert but-2-ene to ethanoic acid?
Oxidation with acidic KMnO4 or Ozonolysis followed by oxidation
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?
toluene is benzene with CH3 reacting this with KMnO4 in acidic solution will produce a benzene with a carboxylic acid (CH3 will be oxidized)
What is the oxidation number assigned to manganese in KMnO4?
Manganese oxidation state = +7 So, it is also called Manganate(VII)
What is the oxidation numbers of manganese in MnO4 1-?
The oxidation number of manganese in KMnO4 is 7+.
Rank these items in order of increasing oxidation number for manganese MnCl2 Mn KMnO4 Mno2 lowest oxidation number?
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
