The boiling points at atmospheric pressure of $HF$,$H_2S$,and $NH_3$ can be arranged in the following order:

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Dipole-dipole interactions are the only non-covalent interactions resulting in hydrogen bond formation.
Reason $R$: Fluorine is the most electronegative element and hydrogen bonds in $HF$ are symmetrical.

$HCl$ is a gas,but $HF$ is a low boiling liquid. This is because

The hydrogen bond is strongest in

Which one of the following does not have intermolecular hydrogen bonding?

Hydrogen bonding does not play any role in the boiling of
