2.12 explain, in terms of dissociation, why hydrogen chloride is acidic in water but not in methylbenzene

Water (H2O) is a polar molecule.
Methylbenzene is a non-polar molecule.
Hydrogen chloride is a polar molecule.

Polars only dissolve in polars.
When hydrogen chloride is dissolved you get +H ions.
These are acidic.

  2. Hydrochloric acid dissociates in water due to the latter's polarity....Hydrochloric acid will never dissociate in toluene as the latter is a non polar organic solvent...
