That’s four unique groups, so we’d say that carbon is a chiral center (aka stereogenic center). If the groups are NH2, OH, CH3, and CH3 the carbon would not be chiral because it only has ... 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.

WebR and S are labels assigned to the stereocenters of a molecule. To easily find the R and S centers, label the four bonded molecules 1 to 4 in order of atomic number. Place the 4 molecule in the back of the chiral center and then in a clockwise (R) or counterclockwise (S) direction label the bonds with atoms 1, 2, 3. Web5.6.1 Diastereomers. It is very common for there to be more than one chirality centers in an organic compound. For the example of 2-bromo-3-chlorobutane below, there are 2 chirality centers, C2 and C3.
