How does butanol have a higher melting point than diethyl ether when they have the same atoms?

I think it is because of the positioning of the Oxygen molecule, as it is more accessible to form a hydrogen bond in the Butanol than in the dimethyl ether

After drawing a Lewis structure for both of these molecules, you can see that the arrangement of the atoms in butanol allow for a Hydrogen bond between H and N, which is a stronger interaction force than just the dipole-dipole interaction forces and London dispersion forces in diethyl ether. As a result, the stronger Hydrogen bond will require more energy to break, resulting in a higher melting point.

Butanol has a higher melting point because it is capable of having a hydrogen bond unlike diethyl ether. This can be seen when drawing out the lewis structures.

Butanol has a higher melting point, due to its ability to form hydrogen bonds.
