Detailed explanation-1: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-2: -Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

Detailed explanation-3: -Strong linkages-called covalent bonds-hold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atoms-in this case oxygen and hydrogen-share electrons with each other.

Detailed explanation-4: -hydrogen bond: A weak bond in which a hydrogen atom in one molecule is attracted to an electronegative atom (usually nitrogen or oxygen) in the same or different molecule. covalent bond: A type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.

Detailed explanation-5: -Every water molecule can be hydrogen bonded with up to three other water molecules (See Fig. 3-7). However, because hydrogen bonds are weaker than covalent bonds, in liquid water they form, break, and reform easily.
