WebStereochemistry is an important issue in any synthesis. This chapter illustrates two key points. First, disconnection should be done at a C C bond where one of the carbon atoms is a stereogenic center. Disconnection of a bond away from the stereogenic center usually leads to a less efficient and less desirable retrosynthesis, and often more ... WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.
