Exercise 11 | Structure and Reactivity
What is the weakest acid?
When comparing the acidity of different molecules (here A and B), it is actually easier to compare the stability of their respective bases (here A' and B').
less stable base = strongest base
strongest base = weakest acid
Fluorine is more electronegative than hydrogen and has an inductive attracting effect:
B' is more stable than A'
A' is the strongest base
A is the weakest acid
