 Why is free rotation around the N-Cα bond of a peptide not allowed? Why is free rotation around the N-C? bond of a peptide not allowed? A Steric clash from amino side chains prevents rotation from occurring. B sp-hybridization due to the partial double bond character prevents rotation from occurring. C Protein tertiary structure prevents rotation from occurring. D The free electron pair of the nitrogen atom repulses the C? atom, preventing rotation from occurring. E Free rotation around the N-C? bond of a peptide is allowed.  |

 Re: Why is free rotation around the N-Cα bond of a peptide not allowed? Ans (B) The partial double bond nature of the peptide bond means that there is not free rotation about the C -- N bond |
