First Midterm Answer Key
... π-electrons are more polarizable than σ-electrons, even though N is less electronegative than O, the C-N triple bond has more π-electrons (2 π-bonds compared to 1), and thus the electrons are more polarized, the dipole moment is thus larger Question 7 (22 pts.) For the indicated localized molecular ...
