Question

Among three bases, X−X−, Y−Y−, and Z−Z−, the strongest one is Y−Y−, and the weakest one is Z−Z−. Rank their conjugate acids, HXHX, HYHY, and HZHZ, in order of decreasing strength.

Answer 1

Rank (in order of decreasing strength):

HZ

HX

HY

Explanation:

The Stronger the base the weaker its conjugate acid.

The strongest base is Y-, then the weakest conjugate acid is HY.

The weakest base is Z-, then the strongest conjugate acid is HZ.

Between them is the pair composed by X- and HX
