In the same conditions of course.

Water is weird. H₂O has MUCH stronger bonds between molecules because it is polar.

Hydrogen has far less desire to attract electrons than oxygen so it is more electronegative. It fulfils this partly by bonding with the hydrogens, “sharing” their electrons.

Because of its electron configuration, the bond between oxygen and hydrogen is angled (the molecule is not a straight line). So the oxygen part of the molecule attracts electrons more than the hydrogen ends.

Because of this it can attract forces not only strongly with its own molecule’s hydrogens but weakly with those of other molecules.

The molecules being attracted together means it is a liquid. Because H₂O is attracted to many organic molecules it is also a good solvent and essential for life.
