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.
