Halogenoalkane hydrolysis

WebThe rates of hydrolysis of different halogenoalkanes can be investigated by: * Alkaline hydrolysis with NaOH(aq)/H2O, reflux: R-X + OH–>R-OH + X * Acidification with dilute nitric acid. This removes excess NaOH, which would otherwise form a precipitate with the silver nitrate in the next stage. Preventing detection of silver halides.

WebCH₃CH₂X + H₂O → CH₃CH₂OH + X⁻ + H⁺ Aqueous silver nitrate is added to a halogenoalkane. The halide leaving group combines with a silver ion to form a silver halide precipitate (AgX). The precipitate only forms when the halide ion has left the halogenoalkane (due to hydrolysis) and so the rate of formation of the precipitate can … WebThe halogenoalkanes have different rates of hydrolysis, so this reaction can be used as a test to identify halogens in a halogenoalkane by measuring how long it takes for the test … right way auto finance inc https://nhoebra.com

Webi) "tertiary carbocation is the most stable as it has 3 alkyl groups surrounding the C-atom which has lost an electron and became a cation" Yes ii) "but the tertiary halogenoalkane which is the basis for this reaction is actually the least stable and thus most reactive?" Sure, if you are considering S N 1 reactions only For S N 2 reactions tertiary alkyl halides are … WebWhich Halogenoalkane undergoes hydrolysis fastest? Rate of hydrolysis increases down group 7 because the bond enthalpy of the carbon-halogen bond decreases down the group meaning less energy is needed to break this bond. This means hydrolysis of iodoalkanes will form a precipitate the fastest.
