Acidity of diprotic acids in aqueous solutions increases in the order

1.	Acidity of diprotic acids in aqueous solutions increases in the order (a) H2S < H2Se < H2Te (b) H2Se < H2S < H2Te (c) H2Te < H2S < H2Se (d) H2Se < H2Te < H2SGive explanation for your Answer
Answer» As the atomic size increases down the group, the bond length increases and the bond strength decreases and the cleavage of E-H bond becomes easier thus, more r.ill be the acidity. Thus, the correct order is H₂S < H₂Se < H₂Te.

Answer»

As the atomic size increases down the group, the bond length increases and the bond strength decreases and the cleavage of E-H bond becomes easier thus, more r.ill be the acidity. Thus, the correct order is

H₂S < H₂Se < H₂Te.
