Answer:
H2O: 100°C
N2O: -88.5°C
NaF: 1414°C
Step-by-step explanation:
H2O is a covalent molecule with strong hydrogen bonds between its molecules, giving it a high boiling point.
N2O - Because N2O has a weaker intermolecular force than H2O, it has a lower boiling point.
NaF is an ionic compound with no covalent bonds, only electrostatic forces between its ions, and thus has the lowest boiling point of the three.
These compounds' boiling points are:
H2O: 100°C
N2O: -88.5°C
NaF: 1414°C
