Strong Acids

[Sofia Q]

What is the relationship between bond of A---H regarding the strength of the acid?

[Brianna Becerra 1B]

The longer the bond, the weaker it is making it easier to be broken. The easier it is broken the stronger the acid. The higher the electronegativity, the shorter the bond. This is seen in HF having a stronger bond than HI.

[SnehinRajkumar1L]

The longer the bond, the stronger the acid.

[KarineKim2L]

The weaker the bond between two atoms, the stronger the acid is. Therefore, HF is a weak acid, while HCl, Hbr, and HI are strong acids. HI is the strongest because the bond between H and I is the weakest.

[Jacob Villar 2C]

Long bonds attribute to stronger acids, since they are weaker bonds, and therefore, the acids can be dissociated to a greater degree.

[Sofia Barker 2C]

The longer the bond, the stronger the acid. Long bonds are weak and thus they are easier to break / dissociate easily. Acids that dissociate completely are stronger, and longer bonds make acids most likely to dissociate completely.
