1Explanation Hydrogen bond is formed between a hydrogen atom and any other electronegative atom such as Nitrogen fluorine iodine chlorine oxygen etc Hydrogen bonds are weak bonds that are formed due to the attraction between the two opposite poles ie positive and negative poles These are weak intermolecular forces that can be easily broken off A simple way to explain hydrogen bonds is with water The water molecule consists of two hydrogens covalently bound to an oxygen Since oxygen is more electronegative than hydrogen oxygen pulls the shared electrons more closely to itself This gives the oxygen atom a slightly more negative charge than either of the hydrogen atoms This imbalance is called a dipole causing the water molecule to have a positive and negative side almost like a tiny magnet Water molecules align so the hydrogen on one See Answer
