Acid/Base bonds

[Anokhi Patel 2B]

Do weak acids have shorter or longer bonds? What determines if an acid is weak or strong?

[AveryAgosto]

Longer bond length means that it is a weaker bond which results in it being a stronger acid.

[Cavalli_1H]

stronger acids have weaker bonds. a strong acid is characterized by how it completely or almost completely dissociates in water. so in order for this to be the case, it makes sense then that acids have weaker bonds.

[Jeremy_Guiman2E]

Strong acids by definition completely (or nearly completely) dissociate in solution. Conversely, weak acids would dissociate much less. Less dissociation as with weak acids means that the molecules are still held together and would therefore have stronger, shorter bonds.

[Muskaan Abdul-Sattar]

Strong acids have weaker bonds (long bonds).

[Javier Perez M 1H]

Good question, it has to do with the components of your acidic molecule. Generally when no O is present just H and some P orbital atom the most electronegative and biggest, towards the bottom makes it more acidic. The more Os are present the more acidic. The higher the overall charge the more acidic. Lastly, if there is an O present in your molecule your P-orbital atom has to be the most electronegative possible and no longer based on radius. There are like 3 of these conditions in the textbook and in one of the latest lectures.
