Question

Could you explain the chemical equation of the following experiment with chemical structure?

3mL of concentrated hydrobromic acid was kept in cool temperature and 1mL of 30% hydrogen peroxide was added. 1mL of cyclohexene was added and 2mL of brine and some dichloromethane was added.

A layer was observed. which layer is aqueous and which is organic?

Repeat extraction for several times by adding more DCM

Transfer teh combined organic layers and add 1mL of saturated NaHSO3. transfer the organic phase with a pipet to a 25mL Erlenmeyer falsk and dry with magnesium sulfate. remove dichloromethane by evaporation.

Explanation / Answer

The reaction described in the problem produces 1,2-dibromocyclohexane. This compound is soluble in DCM (dichloromethane). DCM is immiscible with water and hence the organic layer separates out from the aqueous layer. The product 1,2-dibromocyclohexane is found in DCM, that is in the organic layer which is below the aqueous phase.
