Molecules: Identifying Chiral Centers, Meso Compounds, and

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. WebLabel the circled chiral centers as R/S, and circle the rest of the chiral centers in this compound. arrow_forward Ephedrine (2‑methylamino‑1‑phenylpropanol) is a drug that is used as a decongestant and bronchodilator to treat, among other conditions, the congestion due to the common cold. WebThere are two stereocenters in each of the three molecules. Notice that if you take the second molecule and draw a line connecting the top carbon and the point between the the two carbons with hydroxy groups, it has an axis of symmetry and therefore cannot be chiral. There is no way to draw that axis of symmetry for molecules one and three. cithelpdesk tnt.com.au

Eliminate atoms that cannot be chiral centers. A chiral center is a stereocenter with an atom (usually carbons) attached to four nonidentical substituents. To spot potential chiral centers in a molecule, look for carbons connected to four different groups.
