Question

The increasing order of volatility of hydrides of group 16 elements is (A) H2S < H2O < H2Se < H2Te (B) H2O < H2Te < H2Se < H2S (C) H2O < H2S < H2Se < H2Te (D) H2Te < H2Se < H2S < H2O

Tardigrade Admin · Accepted Answer

The trend of volatility is H2O < H2Te < H2Se < H2S. The high boiling point and therefore low volatility of water is due to the association of H2O molecules through hydrogen bonding. However, hydrogen bonding is not present in other hydrides. The intermolecular forces forces. These forces increase with increase in molecular size and therefore, boiling points increase in moving from H2S and H2Se. between the hydrides (except H2O) are van der Waals

Q. The increasing order of volatility of hydrides of group 16 elements is

$H_{2} S < H_{2} O < H_{2} S e < H_{2} T e$

$H_{2} O < H_{2} T e < H_{2} S e < H_{2} S$

$H_{2} O < H_{2} S < H_{2} S e < H_{2} T e$

$H_{2} T e < H_{2} S e < H_{2} S < H_{2} O$

Q. The increasing order of volatility of hydrides of group 16 elements is

H2​S<H2​O<H2​Se<H2​Te

H2​O<H2​Te<H2​Se<H2​S

H2​O<H2​S<H2​Se<H2​Te

H2​Te<H2​Se<H2​S<H2​O

$H_{2} S < H_{2} O < H_{2} S e < H_{2} T e$

$H_{2} O < H_{2} T e < H_{2} S e < H_{2} S$

$H_{2} O < H_{2} S < H_{2} S e < H_{2} T e$

$H_{2} T e < H_{2} S e < H_{2} S < H_{2} O$
