Strong Acids

Postby DanielleNario1A » Thu Dec 06, 2018 8:49 pm

HF would be considered a weaker acid that HI because the electrons have less space to delocalize?

HF is weaker than HI because Iodine is a larger atom and thus it is going to have a weaker bond with hydrogen. Because of this it can give away the hydrogen very easily making it a stronger acid.

I think that thinking of this aside from the size of atoms, you can think about the electronegativity differences to determine bond strength.

Based off of what the person above me said, the longer the bond length, the weaker it is

yes, HF is weaker than HI. longer bond = weaker

One reason that HF is a weaker acid than HI is because of the stronger bond - it is less likely to donate a proton

HI has longer bond than HF, so it will be more easily dissociated in water, and this results in stronger acidity.
