How does potassium permanganate (KMnO4) react with alkenes?
Potassium permanganate (KMnO4) reacts with alkenes through a process called oxidative cleavage. This reaction breaks the double bond in the alkene, resulting in the formation of diols or ketones, depending on the specific conditions of the reaction.
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.
Why does alkene reacts kmno4?
Alkenes react with potassium permanganate (KMnO4) through a process called oxidative cleavage, where the double bond is broken and oxygen atoms are added to the carbon atoms. This reaction results in the formation of diols (glycols) or ketones and carboxylic acids, depending on the conditions and the structure of the alkene.
What are the Chemical equations to distinguish between alkane and alkene?
Alkenes have a double bond between the carbon atoms (C=C) whereas alkanes have a single bond (C-C). so alkenes are unsaturated compounds, add aqueous solution of Bromine or KMnO4 to both the compounds the decolourization of these reagents confirms the presence of alkenes.
Why is NaOH used in oxidation using KMnO4?
NaOH is used in oxidation reactions with KMnO4 to maintain a basic pH, which helps stabilize KMnO4. This ensures that the permanganate ion (MnO4-) remains in its most reactive form, allowing more efficient oxidation of organic compounds. Additionally, NaOH helps to dissolve solid KMnO4 and facilitates the reaction process.

What is the equation of Heptane KMnO4?
no reaction equation
What is the reaction between KMnO4 and H2O2?
The reaction between KMnO4 (potassium permanganate) and H2O2 (hydrogen peroxide) is a redox reaction where the permanganate ion is reduced to manganese dioxide and oxygen gas is produced. The overall reaction can be represented as: 2 KMnO4 3 H2O2 - 2 MnO2 2 KOH 2 H2O 3 O2
Can you draw the organic products formed from the reaction of 1-methylcyclohexene with KMnO4?
The reaction of 1-methylcyclohexene with KMnO4 forms 1-methylcyclohexan-1,2-diol and 1-methylcyclohexan-1,2-dione as the organic products.
What is the formula for potassium permaangante?
KMnO4, used in a number of titrations as an oxidizing agent, also useful in organic reactions for the same purpose (usually oxidation of alkenes and alkynes).
What is the product when ethanol react with excess acidified kmno4?
When ethanol reacts with excess acidified KMnO4, it is oxidized to form ethanoic acid. The purple color of KMnO4 is decolorized to colorless Mn2+ ions during the reaction.
Why you add h2so4 to the kmno4 titration?
consider the balance chemical equation, suppose the reaction with oxalic acid 2MnO4- + 16H+ + 5C2O4 --> 2Mn+2 + 8H2O + 10CO2 Above reaction shows that the reaction requires a number of protons to occur, H2SO4 is the source of these protons.
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.
