The boiling points at atmospheric pressure of HF, H2S, NH3 can be arranged in the order?

Dear student
Please find below the solution to the asked query:

Boiliing point depends upon the intermolecular forces of attraction.
Boiliing point of HF is highest due to strong hydrogen bonding. Extra amount of energy is required to break these hydrogen bonds and hence boiling point is higher.
NH3 comes next due to weak hydrogen bonds that are possible due to an electronegative N atom.
H2S has least boiling point.

HF>NH3>H2S
