The amide structure is the fundamental linking unit in proteins. Two partial Lewis structures for formamide are shown below. These structures do not show the lone-pair electrons or the formal charges. Experiment shows that formamide is planar, so which is the better representation of the electronic structure, I or II? Is this conclusion consistent with the formal charges on the atoms? Explain the rationale for your answers.
