Correct order of boiling points of the given liquids is:A. H2O > HF > HCl > NH3B. HF > H2O > HCl > NH3C. HF > H2O > NH3 > HClD. H2O > HF > NH3 > HCl

The correct order of boiling points of the given liquids is: H2O > HF > NH3 > HCl.

This is because boiling point is directly related to the strength of intermolecular forces. Water (H2O) has the highest boiling point because it can form two hydrogen bonds per molecule, which are stronger than the dipole-dipole interactions in HF, and much stronger than the dispersion forces in NH3 and HCl. HF can form one hydrogen bond per molecule, making its boiling point higher than NH3 and HCl. NH3 can form one hydrogen bond per molecule, but it is less polar than HF, so its boiling point is lower. HCl can only exhibit dipole-dipole interactions, which are weaker than hydrogen bonds, so it has the lowest boiling point.

So, the correct answer is D. H2O > HF > NH3 > HCl.
