Acidity of diprotic acids in aqueous solutions increases in the order

Question

Acidity of diprotic acids in aqueous solutions increases in the order (A) H2S < H2 textSe < H2 textTe (B) H2 textTe < H2S < H2 textSe (C) H2 textSe < H2 textTe < H2S (D) H2 textSe < H2S < H2 textTe

As on moving down the group bond length increases so liberation tendency of H+ will be more as cleavage of M-H get easier, so acidic nature decreases. H2S < H2 textSe < H2 textTe

Q. Acidity of diprotic acids in aqueous solutions increases in the order

$H_{2} S < H_{2} Se < H_{2} Te$

$H_{2} Te < H_{2} S < H_{2} Se$

$H_{2} Se < H_{2} Te < H_{2} S$

$H_{2} Se < H_{2} S < H_{2} Te$

As on moving down the group bond length increases so liberation tendency of $H^{+}$ will be more as cleavage of M-H get easier, so acidic nature decreases.
$H_{2} S < H_{2} Se < H_{2} Te$

H2​S<H2​Se<H2​Te

H2​Te<H2​S<H2​Se

H2​Se<H2​Te<H2​S

H2​Se<H2​S<H2​Te

As on moving down the group bond length increases so liberation tendency of H+ will be more as cleavage of M-H get easier, so acidic nature decreases. H2​S<H2​Se<H2​Te

$H_{2} S < H_{2} Se < H_{2} Te$

$H_{2} Te < H_{2} S < H_{2} Se$

$H_{2} Se < H_{2} Te < H_{2} S$

$H_{2} Se < H_{2} S < H_{2} Te$
