Sigma bonds and bond rotation ppt课件介绍

Sigma bonds and bond rotation ppt课件内容预览:When we do conformational analysis, we will find that certain types of structural formulas are especially convenient to use. One of these types is called a Newman projection formula and another type is a sawhorse formula. Sawhorse formula are much like other three-dimensional formulas we have used so far. In conformational analyses, we will make substantial use of Newman projections. To write a Newman projection formula, we imagine ourselves taking a view from one atom (usually a carbon) directly along a selected bond axis to the next atom (also usually a carbon atom). The front carbon and its other bonds are represented asand those of the back carbon as.pptSigma bonds and bond rotation To write a Newman projection formula, we imagine ourselves taking a view from one atom (usually a carbon) directly along a selected bond axis to the next atom (also usually a carbon atom).
