Document Summary

Conformers the diferent forms of a molecule crested by the rotaion of bonds. Conformaional analysis the study of the thermodynamic and kineic behavior of conformers. Newman projecions depict the conformaions of ethane: newman projecion an alternaive illustraion to hashed-wedged line structures made by turning the molecule out of the plane of the page and viewing it along the c c axis. Conformers of ethane have diferent potenial energies: torsional strain the change in energy resuling from bond rotaion from the staggered to the eclipsed conformaion. The molecule has its highest energy content at the point of eclipsing: torsional angle degrees of rotaion. Steric hindrance raises the energy barrier to rotaion: steric hindrance the unfavorable interference between the methyl subsituent and the eclipsing hydrogen in the transiion state.
