Question

Given below are two statements:

Statement I: The boiling points of the following hydrides of group $16$ elements increases in the order - $H_{2} O < H_{2} S < H_{2} Se < H_{2} Te$ .

Statement II: The boiling points of these hydrides increase with increase in molar mass.

In the light of the above statements, choose the most appropriate answer from the options given below:

Boiling point increases with molar mass of the compound, and it is also effected by hydrogen bonding.

By considering both the factors, the correct order of boiling points of 16th group hydrides is,

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

$H_{2} O$ have the highest boiling point because of hydrogen bonding.
