acidity

Why are long, weaker A-H bonds more acidic than short, strong bonds?

Long A-H bonds are more acidic than shorter bonds because the longer bond is easier to break and easier to remove the H+.

The longer the bond the more stable the acid is. The resulting conjugate base does not want to attract the H after disassociating.

Longer bonds are weaker, and, thus, easy to break. This means it is easier for H+ to be released, so acids with longer bonds on hydrogen are typically more acidic.

longer bonds stand for less attraction as the valence electrons are further from the nucleus, and the dissociation of acid gives H+ and decrease the pH, so acids with longer bonds will give more H+ ion and thus are stronger acids.
