When hydrogen chloride is dissolved in water the solution formed turns a blue litmus paper to red while the red litmus paper remains red. This is because hydrogen chloride is polar and dissolves in water which is also polar and ionises to produce H+ which are responsible for the acidity of the solution.
In methylbenzene, hydrogen chloride dissolves but does not ionize and therefore the solution has no effect on either a blue or red litmus paper. This because methylbenzene is a non-polar solvent.
