PH3 is a stronger acid than NH3.
PH 3 is a stronger acid than NH 3 .

H2S is a stronger acid than HCl.
H 2 S is a stronger acid than HCl.

HF is a stronger acid than HCl.
HF is a stronger acid than HCl.

NH3 is a stronger acid than HF.

Answer 1

To evaluate the comparisons regarding the acidity of the given compounds:

1. PH3 (phosphine) vs. NH3 (ammonia): PH3 is a weaker acid than NH3. Therefore, the statement "PH3 is a stronger acid than NH3" is incorrect.

2. H2S (hydrosulfuric acid) vs. HCl (hydrochloric acid): HCl is a stronger acid than H2S. Therefore, the statement "H2S is a stronger acid than HCl" is incorrect.

3. HF (hydrofluoric acid) vs. HCl (hydrochloric acid): HCl is a stronger acid than HF. Therefore, the statement "HF is a stronger acid than HCl" is incorrect.

4. NH3 (ammonia) vs. HF (hydrofluoric acid): NH3 is a base and not an acid; HF is an acid. Therefore, the statement "NH3 is a stronger acid than HF" is incorrect.

Based on the evaluations, all the given comparisons are incorrect.
