All the stereoisomers possible for 1,2,3-cyclopentanetriol, with their labeled chiral centers, are to be drawn. Also, the enantiomers and diastereomers that exist for the compound are to be distinguished. Concept introduction: Enantiomers: Two molecules that are mirror images of each other and are non-superimposable. A meso compound is an achiral compound that has chiral centers. It tends to get superimposed on its mirror image that makes it optically inactive, although it contains two or more stereocenters. It has a d -configuration above the plane and an l -configuration below the plane, or vice versa. Diastereomers: Two stereoisomers that have different orientations of atoms around and are not mirror images of each other.

Question

assign the stereochemical configuration of the selected tetrahedral carbon chiral centers (R, S or N (not a chiral center)) and the alkene (E, Z or N (not a stereocenter)) that are indicated by the arrows (note that you do not have to assign the configuration of every chiral center in the molecule). If the atom in question is not a chiral center or is not a stereocenter circle N for neither.

Interpretation Introduction

Interpretation:

All the stereoisomers possible for 1,2,3-cyclopentanetriol, with their labeled chiral centers, are to be drawn. Also, the enantiomers and diastereomers that exist for the compound are to be distinguished.

Concept introduction:

Enantiomers: Two molecules that are mirror images of each other and are non-superimposable.

A meso compound is an achiral compound that has chiral centers. It tends to get superimposed on its mirror image that makes it optically inactive, although it contains two or more stereocenters. It has a d-configuration above the plane and an l-configuration below the plane, or vice versa.

Diastereomers: Two stereoisomers that have different orientations of atoms around and are not mirror images of each other.

If the atom in question is not a chiral center or is not a stereocenter circle N for neither.

Stereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of trans-1,2-dibromocyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry where it exists.In cases where there is more than one answer, just draw one.

Draw tartaric acid - 2,3-Dihydroxybutanedioic acid (-dioic means two carboxylgroups), how many stereo isomers will this molecule have? How many of these isomers will be chiral?
