    1>3>2 Explanation - The acid-base properties of the hydride of an element can be related to its position in the periodic table. In any horizontal row of the table, the most basic hydrides are on the left, and the most acidic hydrides are on the right.On the right-hand side of the row, the acidity increases in the order PH3 < H2S < HCl. This general trend is related to the increasing electronegativity of the element as we move from left to right in any horizontal row. In general. n any vertical column of nonmetallic elements, there is a tendency toward increasing acidity with increasing atomic number. For example, among the group 6A elements the acid dissociation constants vary in the order H2O < H2S < H2Se < H2Te. This order arises primarily because the bond strengths steadily decrease in this series as the central atom grows larger and the overlaps of atomic orbitals grow smaller.  *** This order will be same if we replaced one H with cyclopropyl ring. so the order in case of this will be 1>3>2
