Lecture 11: Peptide Bonds and Exceptions to the Octet Rule

isomers

compounds with the same molecular formula, but different bonding between atoms --> ARE DIFFERENT MOLECULES

equivalent resonance structures

resonance structures that contribute equally to the "average" structure

isomers

compounds with the same molecular formula, but different bonding between atoms --> ARE DIFFERENT MOLECULES

equivalent resonance structures

resonance structures that contribute equally to the "average" structure

non-equivalent resonance structures

resonance structures with greater and lesser contributors to the overall "average" of the structure

planar

involving two dimensions --> peptide bonds are _____ because of resonance structures and partial double bond character which restricts rotation around the central C-N bond
