Strength Of Hydrogen Bond In Water

Hydrogen bonding. Hydrogen bonds b are medium strength attractive intermolecular or intramolecular forces. Hydrogen bonding [] occurs when an atom of hydrogen is attracted by rather strong forces to two (groups of) atoms instead of only one, such that it may be considered to be acting as a bond between them [].

A chemical bond is any force of attraction that holds two atoms or ions together. In most cases, that force of attraction is between one or more negatively charged electrons held by one of the atoms and the positively charged nucleus of the second atom. Chemical bonds vary widely in their strength.
