Acidity Of Diprotic Acids In Aqueous Solutions Increases In The Chemistry Question

Acidity of diprotic acids in aqueous solutions increases in the order

Options

(a) H₂S < H₂Se < H₂Te
(b) H₂Se < H₂S < H₂S
(c) H₂Te < H₂S < H₂Se
(d) H₂Se < H₂Te < H₂S

Correct Answer:

H₂S < H₂Se < H₂Te

Explanation:

The weaking of M-H bond with increase in size of M(where M=s, Se, Te) explains the acid character of hydrides. Since on moving down the group atomic size increases hence bondlength increases and hence removal tendency of H also increases.
