Part 1 (1 point) See Hint Due to its partial double bond character, the peptide bond restricts rotation, constraining atoms to lie within the same peptide plane. Rotation in the peptide backbone is around the two bonds that flank adjacent Ca atoms, between which a peptide plane is formed. Part 2 (1 point) See Hint What is the molecular geometry of the constituents of the peptide plane? Choose one: A. The amide nitrogen is tetrahedral and the carbonyl carbon is...

Which of the following is true about the peptide bond. Choose all true statements. The peptide bond is polar, the N has a partial negative charge and the C has a partial positive charge. The peptide bond is uncharged. The plane of the peptide bond contains the following atoms: the alpha-carbon atom and CO groups of the first amino acid, the NH group and alpha-carbon of the second amino acid. The peptide bond has no double bond character.

Why are double bonds and peptide bonds more rigid than single bonds?
Why are double bonds and peptide bonds more rigid than single bonds?
Why is the peptide bond is considered rigid and planar? Please explain.

Why are double bonds and triple bonds shorter than single bonds?
1. Why are double bonds and triple bonds shorter than single bonds? 2. VSEPR geometry predicts that the bond angles in formaldehyde (CH20), a trigonal planar molecule, will be 120° throughout all three angles. However, analysis showed that the H-C-H bond angle is slightly smaller at 116.5°, while the two H-C-O angles are slightly larger at 121.8°. Explain this difference in the predicted bond angle vs actual bond angle. 3. VSEPR geometry also predicts that the bond angles in tetrahedral molecules is...
