WebAnswer: There is a great misconception about the “power” of hydrogen bonds. Yes, they provide a great deal of binding energy (typically 0.5–1.5 kcal/mole for uncharged hydrogen bonds (H-bonds); up to 4.5 kcal/mole for charged ones), and also provide stabilization of many aqueous inter- and intra-... WebThe hydrogen bonds are formed by hydrogen atoms and other atoms like nitrogen and oxygen when their electropositivity attracts the electronegative atoms of this other atoms. Van der waal forces are are those that come about as a result of the number of electrons in n atom and there size,the larger the size the weaker the van der waal forces get.
