hydrogen bonding happens BETWEEN MOLECULES not within a single molecule hydrogen bonds are formed when two hydrogens are connected to the same element in multiple molecules when elements are sharing electrons which one has the more negative charge the one with the higher electronegativity hydrogen bonds form because the more electronegative element in one molecule attracts the less electronegative element in the other molecule what elements can make hydrogen bonds O, F, N
