What happens when hexene reacts with cold neutral and dilute potassium dichromate?
One would expect that the reaction between an alkene and cold, dilute potassium dichromate is an oxidation to a bifunctional alcohol at the carbons in the double bond. The result is also called a vincinal diol or a glycol.
The reaction should be similar to the reaction of an alkene with cold, dilute potassium permangante, however, dichromate is a milder oxidizing agent and may not be as effective.
The mechanism for this reaction involves the formation of an intermediete 'ester' with the metal at the carbons of the double bond, breaking the double bond. The it can be shown that the resonance structure of the intermediete complex transfers electron density to the ester linkage and protonates from water at both of the ester sites completing the oxidation.

Does the pH of the solution increase decrease or stay the same when you add solid potassium chloride to dilute solution of potassium hydroxide?
The pH of the solution will decrease when solid potassium chloride is added to a dilute solution of potassium hydroxide. This is because potassium chloride is a neutral salt that will not affect the pH significantly, while potassium hydroxide is a strong base. The addition of more chloride ions will reduce the concentration of hydroxide ions in the solution, leading to a decrease in pH.
How do you prepare 1 N potassium dichromate?
prepare a concentrated aqueous solution of di chromate and add solid KOH warm till orange colour change to yellow and then filter the solution the filtrate is allow to evaporate and get solid potassium chromate.
Chlorine gas plus cold dilute potassium hydroxide?
When chlorine gas is added to cold dilute potassium hydroxide, it forms potassium hypochlorite (KClO) and potassium chloride (KCl). This reaction is represented by the equation: Cl2 + 2KOH -> KClO + KCl + H2O.
How is potassium hydroxide different from dilute nitric acid?
Potassium hydroxide is a strong base, while dilute nitric acid is a strong acid. Potassium hydroxide is alkaline, whereas dilute nitric acid is acidic. They have different chemical properties and uses in various processes.
What is the chemical reaction of aluminum oxide and dilute potassium hydroxide?
The reaction between aluminum oxide and dilute potassium hydroxide produces potassium aluminum oxide and water. The balanced chemical equation for this reaction is: Al2O3 + 6KOH -> 2K3Al(OH)6.
