Benzene is a stable aromatic compound that does not readily undergo oxidation by potassium permanganate (KMnO4) due to the lack of reactive functional groups. Phenol or other compounds with labile hydrogen atoms are more susceptible to oxidation by KMnO4. Benzene's stable ring structure prevents it from being easily oxidized by KMnO4.
What else can I help you with?
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.
How will you convert benzene to benzaldehyde?
Benzene can be converted to benzaldehyde through a reaction involving oxidation using a strong oxidizing agent, such as chromic acid (H2CrO4) or potassium permanganate (KMnO4). The oxidation of benzene results in the formation of benzaldehyde.
Why is benzene stable to towards KMnO4 oxidation?
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.
Chemical symbol for permanganate?
The formula for potassium permanganate is KMnO4
Can KMnO4 be acidified with HCl and HNO3?
Yes, potassium permanganate (KMnO4) can be acidified with both hydrochloric acid (HCl) and nitric acid (HNO3) to increase its reactivity. Acidification helps to enhance the oxidizing power of KMnO4 in redox reactions.
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.
Equation for benzene plus KMnO4?
Benzene does not react directly with potassium permanganate (KMnO4) under normal conditions. Benzene is a stable aromatic compound and does not undergo typical alkene or alkane reactions with oxidizing agents like KMnO4.
How do aldehyde's react?
aldehyde is less stable than benzene so it react readily toward kmno4
How will you convert benzene to benzaldehyde?
Benzene can be converted to benzaldehyde through a reaction involving oxidation using a strong oxidizing agent, such as chromic acid (H2CrO4) or potassium permanganate (KMnO4). The oxidation of benzene results in the formation of benzaldehyde.
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).

What are kmno4?
acidicness number of kmno4

Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.
Why is suger insoluble in benzene?
Sugar is insoluble in benzene due to the differences in their chemical properties. Sugar is a polar compound with numerous hydroxyl groups, making it soluble in water. Whereas benzene is a nonpolar solvent that cannot form hydrogen bonds with the polar sugar molecules. This mismatch in polarity prevents sugar from dissolving in benzene.
What is is the formula for potassium permanganate?
KMnO4.
