Draw the unique stereoisomers for 2-chloro-2,3-dimethylpentane. Show stereochemistry clearly. To ensure proper grading, explicitly draw all four groups, including wedge/dash bonds, around a chirality center. Indicate whether the compounds could exist in an optically active form.
Homework Answers
The concept of this problem is stereochemistry. Stereochemistry is a branch of chemistry which deals with the spatial arrangement of atoms in space. This phenomenon proves that compounds having same molecular formula or identity can possess different physical and chemical properties.
Optical isomers are the compounds having same molecular arrangement and formula and different optical activity.
The molecule is optically active and the chiral carbon is shown below.
Stereoisomers configuration of the given organic compounds are
The given compound can exist in optically active form and the stereoisomers are,

first isomer you should draw is provided. Assign R or S
configuration to each chirality center in the additional isomers.
Indicate the stereochemical relationship (diastereomers,
enantiomers, meso compounds) between the first isomer and each of
the others. The configuration for the Fischer Projection has been

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images.
