A hydrogen bond is the electrostatic attraction between two polar groups that occurs when a hydrogen (H) atom covalently bound to a highly electronegative atom such as nitrogen. So In Terms  nitrogen (N), oxygen (O), or fluorine (F) help form The bonds

to form Hydrogen bond , the molecules must have electronegative elements like fluorine, oxygen or nitrogen !!

like water , it has oxygen and other side hydrogen this it can form Hydrogen bond !!
