5) The same peptide if exhibits as resonance structure as indicated above, then what is the hybridization of a. The Carbonyl Carbons? b. The Nitrogens? 6) Resonance prevents some of the bonds from free rotations at the peptide bond. Given what you know about the resonance forms and hybridization, indicate the freely rotatable bonds in the dipeptide shown below, by circling and/or putting an arrows. 7) In the above peptide, draw a rectangle (or rectangles) around the atoms that are co-planar (within the same plane). Hint: There are two separate sets of coplanar atoms, with one atom belonging to both 8) If one of the \( \mathbf{R} \) groups above was Proline, which bond cannot rotate anymore) (Hint: Think about the proline structure)
