WebThe order of acidic strength is as follows: Water < Acetic acid < Hydrochloric acid Since Hydrochloric acid HCl is a strong acid. Thus it has the highest acidic strength or it can dissociate completely, acetic acid CH 3 COOH is a weak acid as it dissociates partially into H + ions while water H 2 O is a neutral solution. WebThe order of decreasing acidity is III > IV > I > II. Look for an extreme of the most or least acidic group and eliminate answer choices. The most acidic compound is III because the NO2 group is the strongest electron withdrawing group, and it stabilizes the conjugate base through resonance.
