In other words, stereoisomers have the same types of bonds, but different spatial arrangements and different chemical properties.5.10: Diastereomers and Physical Properties. In a pair of diastereomers, some chiral centers are the same and some are opposite. The molecule is neither identical to nor the mirror image of its diastereomer. Threitol is a metabolite closely related to carbohydrates. D-threitol is the enantiomer of L-threitol. Enantiomers are stereoisomers that are non-superimposable mirror images, meaning that one enantiomer will be the mirror image of the other enantiomer. In order to draw an enantiomer, you can determine the stereocenter, then swap the two groups attached to the stereocenter. Questions. Tips & Thanks.This organic chemistry tutorial video provides practice answering questions involving stereochemistry.Erythritol is a diastereomer to both L-threose and D-threose.

Tartaric acid, C 4 H 6 O 6, is an organic compound that can be found in grape, bananas, and in wine. The structures of tartaric acid itself is really interesting. Naturally, it is in the form of (R,R) stereocenters. Artificially, it can be in the meso form (R,S), which is achiral. The two structures have the same molecular formula and the same connectivity, therefore they must be stereoisomers. They each have four chiral centers, and the configuration is different at two of these centers (at carbons #3 and #4). They are diastereomers. Now, look at the structures of D -glucose and D -mannose. Diastereomers, on the other hand, have different physical properties, and this fact is used to achieve resolution of racemates. Reaction of a racemate with an enantiomerically pure chiral reagent gives a mixture of diastereomers, which can be separated. Reversing the first reaction then leads to the separated enantiomers plus the recovered reagent.Sự khác biệt chính giữa enantiomers và diastereomers là cái trước được tìm thấy dưới dạng hình ảnh phản chiếu trong khi cái sau thì không.
