Why does naf have a higher boiling point than hf? 4.0) is 1.8 so H-F is a polar covalent compound. This means HF exhibits dipole-dipole interaction. Since NaF has the strongest intermolecular force, thus NaF would have the highest melting point.
Why does HF not have a high boiling point? Due to the higher partial charges on H and F in HF, a hydrogen bond between HF molecules is stronger than that between NH3 molecules. The higher boiling point of HF is thus due to stronger H-bonds.
Why does HF have higher boiling point? Hydrogen bonding is the strongest intermolecular force. Due to strong intermolecular forces, the molecules of HF will be tightly packed in a lattice. Thus, HF will have the highest boiling point since the boiling point of a system depends upon the intermolecular interactions.
Why does HF have a low boiling point? So more hydrogen bonding per molecule of water than per molecule of HF causes HF to have lower bp than water. In determination of Boiling point we have to consider the intermolecular forces rather than intramolecular forces.

Which one has the highest boiling point sif4 or sih4?
SiF4 (-86 C) has a higher boiling point than SiH4 (-112 C). SiF4 is larger and has more electrons, making it more polarizable. This increases the induced dipole-induced dipole forces.
