Water is said to be highly cohesive because water molecules interact with one another through hydrogen bonds.
Cohesion is the property of molecules sticking to each other. This property is mostly seen in water. Foe cohesion, the attraction should be mutual between both the particles or molecules. Hydrogen bonding in water is a very strong bond that establishes the property of cohesion.
Hydrogen bonds are the non-covalent bonds. It is an intermolecular bond between an electronegative and an electropositive atom. The electropositive atom is generally hydrogen and electronegative atom could be fluorine, oxygen or nitrogen.
