Hydrogen bonds exhibit the stronger intermolecular force, and water is a polar molecule, so the hydrogen bonding create strong forces which take more energy to break (causing the surface tension of water), and due to the polarity water molecules “stick” to one another which causes the edges to rise up in a tube, forming a meniscus 
 
        
             
        
        
        
they can cause a toxic effect or failure of therapy depending on the drug-nutrient combinations
