What is hydrolysis of halogenoalkanes?

Hydrolysis is decomposition of a chemical due to reaction with water. hydrolysis of halogenoalkanes is a nucleophilic substitution type of reaction.

What happens if NaOH is used to hydrolyse halogenoalkanes?

The hydrolysis of halogenoalkanes is a nucleophilic substitution reaction. In this investigation the nucleophile is water. If NaOH is used to hydrolyse the halogenoalkanes, then any excess NaOH has to be neutralised by HNO3 before adding AgNO3. Write an equation for the reaction of 1-bromobutane with water. In these reactions a precipitate forms.

Which aqueous solution is used to make a halogen iodoalkane reaction?

An aqueous solution of sodium hydroxide (NaOH) or potassium hydroxide (KOH) with ethanol is used This reaction is very slow at room temperature, so the reaction mixture is warmed The rate of this reaction depends on the type of halogen in the halogenoalkane Fluoroalkanes do not react at all, but iodoalkanes have a very fast rate of reaction

How do you compare the rate of reaction between haloalkanes and hydrolysis?

The rate of reaction can be compared by carrying out the reaction in the presence of silver ions. The halogen atoms in haloalkanes are covalently bonded to carbon and give no precipitate of a silver halide. Hydrolysis releases halide ions, which immediately precipitate as the silver halide.
