Examining Relative Hydrogen Bond Strength Within N-Methyl Formamide

The basis of the hydrogen bond is taught in every general chemistry class at the University of Minnesota Morris. However gaining a three dimensional view of the bonding is hard to achieve from just a textbook. Through varying the concentration of the salt KCl (potassium chloride) the visual experience of how hydrogen bonds work was examined. Using nuclear magnetic resonance(NMR) the effect of increasing the KCL was visualized. As the concentration is increased the effect of the KCl is increased in a seemingly linear fashion. Over the course of a ten sample spread varying concentrations from 0.001 M to 1M it was concluded that the hydrogen bond strength is reduced as the concentration of the potassium chloride (KCl) is increased. There is evidence to show that with a salt being added to a protic solution the proton will be shifted at a greater rate with an ever increasing concentration, and the bond strength is impacted. However the trend of the proton shift reached an asymptotic point after the 0.325 M concentration. The expected trend was observed otherwise illustrating that as the concentration of the KCl was increased the proton of the N-Methyl formamide was shifted, showing that the bond strength was increasing as the salt concentration increased.
