7. Explain why hydrogen selenide is a stronger acid than hydrogen sulfide.

Question

Question

Answer 1

Answer #1

S and Se are in same group of periodic table.

We know size of atom increases as we move down a group.

So, Se is larger than S atom

So, bond length H-Se is larger than H-S.

So, its easier to break H-Se bond as compared to H-S bond.

This makes H2Se a stronger acid as compared to H2S

Why is it that HClO is a stronger acid than HBrO, when HBr is a stronger acid than HCl? I thought that more electronegative atoms created stronger bonds with hydrogen and so therefore made it more difficult for those acids to dissociate.
