why does a peptide bond behave like a double bond? Because the C-N bond has some double-bond character, the peptide bond is flat, meaning that the nitrogen and carbonyl carbon atoms both have trigonal planar geometries. Figure 12 Resonance stabilization causes the peptide bond to have double-bond character.
Why do peptide bonds act like double bonds? A peptide bond forms when the carboxylic acid group (R-C[O]OH) of one amino acid reacts with the amine group (R-NH2) of another. The resulting molecule is an amide with a C–N bond (R-C(O)-NH-R). While drawn as a single bond, the peptide bond has partial double bond character that enforces a well-defined flat structure.
Is a peptide bond a double bond? The peptide bond is a stable covalent bond and is said to be a rigid planar bond because it has a partial double bond character. The evidence that shows this partial double bond character is from the length of the bond. It is 0.13 Angstrom shorter than the C-N single bond yet not as short as a double bond.
