why is ethanol used in hydrolysis of halogenoalkanes
Middle. - The reason why ethanol is added is because the halogenoalkanes are immiscible with just silver nitrate, however ethanol makes the solution of silver nitrate and the halogenoalkanes miscible. And doesn't interfere with the reaction in anyway, it is a helping spectator.* Monitor the test tubes under room temperature until a precipitate is seen. In which case a note must be made of the time. - The formation of a precipitate shows the rate of hydrolysis of the haloalkanes.nd doesn't interfere with the reaction in anyway, it is a helping spectator. * Monitor the test tubes under room temperature until a precipitate is seen.

Testing for halogenoalkanes Silver nitrate solution can be used to find out which halogen is present in a suspected halogenoalkane. The most effective way is to do a substitution reaction which turns the halogen into a halide ion, and then to test for that ion with silver nitrate solution.Doing the reaction.ackground. In this case, various halogenoalkanes are treated with a solution of silver nitrate in a mixture of ethanol and water. Nothing else is added. After varying lengths of time precipitates appear as halide ions (produced from reactions of the halogenoalkanes) react with the silver ions present.
