How is a hydrogen bonds different from the convalent bonds that connect each water molcule's atoms?

Answer 1

covalent bond is the sharing of 2 electrons form each atom while in hydrogen bond there is no sharing of electrons.

Hydrogen bond is partial bond due to attraction of Hydrogen atom with negative charge of other molecule so it is having only electrostatic attarction.

Answer 2

Hydrogen bonds are weaker and temporary bonds formed between hydrogen atoms of one molecule and electronegative atoms of another molecule, such as oxygen or nitrogen. Covalent bonds, on the other hand, are strong bonds where atoms share electrons to form stable molecules. In water, covalent bonds connect the hydrogen and oxygen atoms within a water molecule, while hydrogen bonds form between different water molecules.
