Quizplus · Accepted Answer

The order of decreasing acidity is determined by the stability of the conjugate base. The more stable the conjugate base, the weaker the acid. Among the given compounds, H₂O has the most stable conjugate base, as the negative charge is located on the oxygen atom, which is more electronegative than sulfur. Hence, it is the weakest acid. On the other hand, CH₂ has the least stable conjugate base, as the negative charge is located on the less electronegative sulfur atom. Hence, it is the strongest acid. Therefore, the correct order of decreasing acidity is A > E > C > D > B.
