$CH_3-CH_2-COOH$ $\mathop {\xrightarrow{{(i)\,AgN{O_3}}}}\limits_{(ii)\,B{r_2}/\Delta } $ $[X]$
$[X]$ will be :
Statement $I$: The boiling point of hydrides of Group $16$ elements follow the order
$\mathrm{H}_2 \mathrm{O}>\mathrm{H}_2 \mathrm{Te}>\mathrm{H}_2 \mathrm{Se}>\mathrm{H}_2 \mathrm{~S}$.
Statement $II$: On the basis of molecular mass, $\mathrm{H}_2 \mathrm{O}$ is expected to have lower boiling point than the othe members of the group but due to the presence of extensive $\mathrm{H}$-bonding in $\mathrm{H}_2 \mathrm{O}$, it has higher boiling point.
In the light of the above statements, choose the correct answer from the options given below:
Given that molar mass of n-octane is $114 \;g\; mol ^{-1}$
