    π Electron Effects on Chemical Shift: Overview

    An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0, resulting in...

    Electron Affinity

    The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

    π Electron Effects on Chemical Shift: Aromatic and Antiaromatic Compounds

    In aromatic compounds, such as benzene, the circulation of (4n + 2) π-electrons sets up a diamagnetic or diatropic ring current around the perimeter of the molecule. This current induces a magnetic field that opposes the external field inside the ring and reinforces it on the outside. The protons in benzene are deshielded and exhibit high chemical shifts in the range 6.5–8.5 ppm. The shielding effect at the center of the ring is evident in complex aromatic molecules, such as annulenes. In...

    Exceptions to the Octet Rule

    Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

    Electrophilic Addition of HX to 1,3-Butadiene: Thermodynamic vs Kinetic Control

    The addition of a hydrogen halide to 1,3-butadiene gives a mixture of 1,2- and 1,4-adducts. Since more substituted alkenes are more stable, the 1,4-adduct is expected to be the major product. However, the product distribution is strongly influenced by temperature; low temperature favors the 1,2-adduct, whereas the 1,4-adduct is predominant at high temperature.
