Determinig Strength of Acids

Postby Payton Schwesinger 1J » Tue Dec 05, 2017 1:36 pm

When looking at a group of acids and trying to determine which one is stronger, which is more important? Bond length or electron pulling power (electronegativity)? Do you determine only move on to looking at electron pulling power if the bond lengths are the same?

From what I understand, I believe it depends on the type of molecule. For instance, if you're comparing HCl vs. HF, you can determine that HCl is a stronger acid by looking at the bong length (HCl has a long, weak bond). However, if you're comparing HClO2 vs. HClO, you can determine that HClO2 is a stronger acid because it has a higher electron affinity. Also, if you want to compare HClO4 vs. H3PO4, you can determine that HClO4 is the stronger acid because it is more electronegative.

I hope this helped!
