WebNov 22, 2024 · Re: CHF3 boiling point [ENDORSED] CHF3 is a polar molecule due to the F atom having more electrons than a H atom creating a dipole moment with the electrons shifting towards the F atom. This creates a polar molecule allowing for dipole dipole interactions which are stronger than the Dispersion forces of the symmetrical CF4.
