Potassium permanganate and hexane do not react because hexane is an alkane and therefore has no double bonds. Hexene on the other hand is an alkene and can indeed react with potassium permanganate.

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.)

there is no product because alkanes do not react with any thing really

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.....


Why is potassium manganate 7 more soluble in hexane than water?

it is more soluble as hexane is non polar and potassium manganate is also non polar substances with like polarities mix so potassium manganate is more soluble in hexane


What is more flammable hexane or potassium sulfate?

Hexane is a highly flammable liquid, C6 H14. Potassium sulfate is an inorganic salt. You'll never get it to burn.


How do you store potassium safely?

Potassium is stored in not aqueous or non-protic solvents such as kerosene or hexane


Is potassium sulphate soluble in hexane?

No it dosent, hexane has only London forces, while HydrogenChloride has dipole dipole-dipole forces as well. The hexane can therefore not break through the structure of HCl and cannot mix evenly with it.


What is the equation of hexane react with chloroform?

They are not reacting. but they are mixing together.


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


How do you find the boiling point of hexane at 1.5 ATM?

you can use the Clausius-Clapeyron equation if you know the temperature of hexane at 1.5 ATM


What happens when acetylene reacts with alkaline potassium permanganate?

depends on the ratio and conditions really, if there is enough you will make co2 water manganese 2,3 oxide and potassium oxide if not you will make c2 h2 o2 or some other partially oxidized hydrocarbon


In which is KNO3 soluble benzene hexane or water?

Potassium nitrate is soluble in water, as it is an ionic solid. When dissolved in water, potassium nitrate will form an aqueous solution of potassium and nitrate ions.


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.
