The reaction between hexane and potassium permanganate is a combustion reaction that produces carbon dioxide and water as products. The balanced equation is C6H14 + 19/7 KMnO4 → 6 CO2 + 14 H2O + 19/7 MnO2 + K2MnO4.
Hexane will not react with concentrated potassium permanganate even at temperatures over 100 deg. C and at pH values below 1.0. The two compounds may react under very extreme conditions such as at temperatures over 300 deg. C and at pressures over 100 atm. I don't know for sure, although I doubt a reaction would occur even under such harsh conditions. Alkanes, like hexane, are generally inert to nearly all compounds. A radical is normally required to get an alkane to react, therefore hexane will react with species such as a chlorine atom (Cl•) or a peroxide radical (ROO•).
I wanted to make sure that you did not mean "hexene" instead of "hexane." Even cold, dilute permanganate will easily react with hexene. The product(s) from a hexene and permanganate reaction is (are) sensitive to, and depend(s) on, the pH, the reaction temperature, and the permanganate concentration. A hot, concentrated and acidic permanganate solution will convert hexene into at least one carboxylic acid. Each of the two carbons that form the double bond in hexene would be oxidized to a -COOH group. Thus, each molecule of 3-hexene would form two molecules of butanoic acid. The other two possible hexenes, 1-hexene and 2-hexene, would be converted into two different carboxylic acids. (4-hexene is the same molecule as 2-hexene and 4-hexene is also not the correct name of the compound.)

Another test for hexane and hexene apart from bromine?
Another test to differentiate between hexane and hexene is performing a reaction with potassium permanganate in acidic conditions. Hexane will not react with potassium permanganate, while hexene will undergo a color change as the double bond is oxidized by the permanganate ion.
What is more flammable hexane or potassium sulfate?
Hexane is more flammable than potassium sulfate. Hexane is a highly flammable liquid that can easily ignite when exposed to a flame or spark, while potassium sulfate is a solid compound that is not flammable under typical conditions.
What is the balanced decomposition chemical equation for hexane?
The balanced decomposition chemical equation for hexane (C6H14) is: 2C6H14 → 6C + 7H2
Which observations are made in the reaction of hexane with bromine water?
The observation in the reaction of hexane with bromine water is that the color of bromine water changes from orange to colorless as the bromine is being added to the hexane. This indicates that a reaction between hexane and bromine is taking place, forming a colorless product.
How do you find the boiling point of hexane at 1.5 ATM?
To find the boiling point of hexane at 1.5 ATM, you can use the Clausius-Clapeyron equation, which relates temperature and pressure to the enthalpy of vaporization. By knowing the normal boiling point of hexane and its enthalpy of vaporization, you can calculate the boiling point at 1.5 ATM.

Write the chemical reaction between cyclopentene and potassium permanganate?
cyclopentene reaction with potassium permanganate. If cyclohexene gives a diacid (two acid groups in a opened ring), I think that is should yield a pentane with two acid groups, one in each end....it could give more products like CO2 and H2O, by breaking the bonds, you could get a lot of compounds, depending which bonds could break.....
Is potassium sulphate soluble in hexane?
No, potassium sulfate is not soluble in hexane as it is a polar compound and hexane is a nonpolar solvent. Solubility depends on the nature of the solute and solvent; in this case, the polarity mismatch makes potassium sulfate insoluble in hexane.
Why is potassium manganate 7 more soluble in hexane than water?
Potassium manganate 7 is more soluble in hexane than in water because it is a nonpolar solvent like hexane. Nonpolar solutes tend to dissolve better in nonpolar solvents, while water is a polar solvent. Therefore, the solubility of potassium manganate 7 is higher in hexane than in water.
What is more flammable hexane or potassium sulfate?
Hexane is more flammable than potassium sulfate. Hexane is a highly flammable liquid that can easily ignite when exposed to a flame or spark, while potassium sulfate is a solid compound that is not flammable under typical conditions.
What is the balanced decomposition chemical equation for hexane?
The balanced decomposition chemical equation for hexane (C6H14) is: 2C6H14 → 6C + 7H2
How do you store potassium safely?
Potassium is stored in not aqueous or non-protic solvents such as kerosene or hexane
In which is KNO3 soluble benzene hexane or water?
KNO3 is soluble in water but not in benzene or hexane.
What happens when acetylene reacts with alkaline potassium permanganate?
When acetylene reacts with alkaline potassium permanganate, it is oxidized to form carbon dioxide and water. This reaction is exothermic, releasing energy in the form of heat. The purple color of the potassium permanganate solution fades as it is reduced during the reaction.
What is difference between hexane and n-hexane?
Hexane is a hydrocarbon with the chemical formula C6H14. n-hexane is the unbranched isomer of hexane as there exists four more branched isomers of hexane
Which observations are made in the reaction of hexane with bromine water?
The observation in the reaction of hexane with bromine water is that the color of bromine water changes from orange to colorless as the bromine is being added to the hexane. This indicates that a reaction between hexane and bromine is taking place, forming a colorless product.
What kind of bonds exist between Hexane molecules?
There are no bonds between hexane molecules. There are intermolecular forces, called London Dispersion Forces which attract other hexane molecules.
