Among three bases, x-, y-, and z-, the strongest one is y-, and the weakest one is z-. rank their conjugate acids, hx, hy, and hz, in order of decreasing strength.

Bases:

x - middle strength

y - strongest base

z - weakest base

The bases and conjugate acids have an inverse strength. The stronger the conjugate base, the weaker its conjugate acid.

I am considering two scenarios:

Scenario 1:

y - strongest base; hy - weakest conjugate acid

x - middle base; hx - middle conjugate acid

z - weakest base; hz - strongest conjugate acid

hz → hx → hy

Scenario 2:

y-strongest base; hy - weakest conjugate acid

x-middle base; hx - strongest conjugate acid

z-weakest base; hz - middle conjugate acid

hx → hz → hy
