Question

Which is the non covalent bonds responsible for the high melting and boiling points of water?

Answer 1

A non-covalent interaction differs from a covalent bond in that it does not involve the sharing of electrons,[1] but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule. The chemical energy released in the formation of non-covalent interactions is typically on the order of 1-5 kcal/mol (1000–5000 calories per 6.02 x 10^23 molecules).[2]Non-covalent interactions can be classified into different categories, such as electrostatic, π-effects, van der Waals forces, and hydrophobic effects.[3][2]
