WebChemistry questions and answers. 3) a) Determine if each molecule is either chiral, achiral, or achiral meso (circle as shown). b) Determine if each labelled carbon is R, S or can't be labelled as Rors c) Determine if each compound as optical active or optically inactive. First structure has been completed to show you how to answer the question. WebOnce the two molecules you are comparing look more similar you may be able to see that they are actually the same molecule (eg meso compounds) or are actually enantiomers. So for the example above (diol example) you can rotate molecule 4 by 180 degrees in the plane of the page and see that it's actually identical to moIecule 3.

WebJun 12, 2016 · You draw stereochemical formulas of the isomers and look for superimposable mirror images. A molecule must have restricted rotation — a ring or a double bond — in order to have cis and trans isomers. Pentane-2,3-diol has neither a ring nor a double bond, so it has no cis or trans isomers. Here are the Fischer projections of its … WebMeso forms If the two chiral centers in a molecule contain the same four groups, then it is possible that one center is just an “internal reflection” of the other. (Since the groups are the same, we will color both of them red when we indicate R/S.) shw peterson real estate
