Why are acids with weaker bonds stronger?

[Evan Sang 1K]

I saw in the textbook that the greater the electron affinity/electronegativity of the central atom, the stronger the acid is, but also saw in an example that the weaker the central atom-H bond is, the stronger the acid is. Could anyone explain why this is?

In terms of bond strength, weaker bonds means that the H+ proton can be removed easier, which we know is a characteristic of strong acids.

Strong acids dissociate completely --> so their bonds have to break more easily --> so their bonds must be weaker

Hope this helps.
