Q. Given below are two statements :
Statement I: The boiling points of the following hydrides of group $16$ elements increases in the order -
$H _{2} O < H _{2} S < H _{2} Se < H _{2} Te \text {. }$
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 :

NEETNEET 2022The p-Block Elements - Part2

Solution:

Hydrides of group $16^{\text {th }}$
$\underset{\text{H-bond}}{H _{2} O} \,\,\, \underbrace{ H _{2} S \quad H _{2} Se \quad H _{2} Te }_{ H \text {-bond }}$
B.P. $\rightarrow H _{2} S < H _{2} Se < H _{2} Te < H _{2} O$
