To determine which comparison is correct, let's evaluate each statement based on the general properties of acids and their strength.
1. **NH3 is a stronger acid than HF.**
- This is incorrect. Ammonia (NH3) is a weak base and is significantly weaker than hydrofluoric acid (HF), which is a weak acid but stronger than NH3.
2. **H2S is a stronger acid than HCl.**
- This is incorrect. Hydrochloric acid (HCl) is a strong acid, while hydrogen sulfide (H2S) is a weak acid.
3. **PH3 is a stronger acid than NH3.**
- This is generally incorrect. Phosphine (PH3) is a weak base and is not considered stronger as an acid compared to ammonia (NH3).
4. **HF is a stronger acid than HCl.**
- This is incorrect. HCl, being a strong acid, is stronger than HF, which is a weak acid.
Based on this analysis, none of the comparisons provided are correct. However, if you must choose the one that comes closest to an acceptable statement (the last one is more comparative), it is essential to clarify that HCl is indeed stronger than HF. Thus, there is no correct comparison among those provided.
