Answer:
Step-by-step explanation:
The fact that HF is a stronger acid than HON indicates that the conjugate base of HF (F-) is weaker than the conjugate base of HON (ON-). In other words, F- is a stronger base than ON-.
Therefore, the correct statement is:
b. F- is a stronger base than CN-.
Statements a, c, and d cannot be determined from this fact.
