The bond present between water molecules is a hydrogen bond.

Option 1: An electrovalent bond, also known as an ionic bond, is formed between atoms that have significantly different electronegativities, resulting in the transfer of electrons. This type of bond is not present between water molecules.

Option 2: A covalent bond is formed when atoms share electrons. While water molecules do form covalent bonds between the oxygen and hydrogen atoms within each molecule, the bond between different water molecules is not covalent in nature.

Option 3: The correct answer. A hydrogen bond is a weak attraction between the positive end of one water molecule (the hydrogen atom) and the negative end of another water molecule (the oxygen atom). This bond is important for the unique properties of water, such as its high boiling point and surface tension.

Option 4: Vander Waals forces, which include London dispersion forces, dipole-dipole interactions, and hydrogen bonding, are intermolecular forces that hold molecules together. While hydrogen bonding is a specific type of Vander Waals bond, it is more accurate to specifically describe the bond between water molecules as a hydrogen bond rather than a general Vander Waals bond.

In conclusion, the bond present between water molecules
