Question

Why do alkyl halides undergo hydrolysis more easily than arylhalides?

Answer 1

It is because of the resonance of aryl halides which makes it stable and thus has less reactivity.
whereas the alkyl halides doesnot have any resonance so to get stability it undergoes hydrolysis.
Here the aryl halide is already stable and so it doesnot react.

Answer 2

$\huge\textcolor{red}{\texttt{Answer :-}}$

In aryl halides, there is double bond character in carbon halogen bond and the bond is less polar.

So, it is more difficult to break this bond as compared to single bond, in alkyl halides.Hence, alkyl halides undergo hydrolysis more readily than aryl halides.
