Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Usage wedge-and-dash bonds because that the substituent groups, and also be sure that they are drawn on the external of the ring, adjacent to each other. The skeletal framework of one molecule is had to suggest the appropriate format; modify the X's ~ above the provided structure to create the very first stereoisomer.

Stereo isomers space isomers that have same molecule formula and constitutions roughly the atom yet differ in their spatial plan of groups roughly the atom. Stereo isomers are largely of two varieties (i) Enantiomers (ii) Diastereomers.


• Enantiomers: Enantiomers space stereo isomers, which room non-super imposable mirror images.

Isomers are mirror images but not supervisor imposable.

• Diastereomers: Diastereomers room stereo isomers, which space non-super imposable non winter images. Isomers space neither super imposable nor mirror images.

• The total variety of stereo isomers for a link is 2n\rm2^\rmn2n , whereby “n” is the number of chiral centers current in the compound.

• If aircraft of the contrary is existing in the isomer, the total variety of stereo isomers because that a link is 2n−1\rm2^\rmn\rm - 12n−1 , whereby “n” is the variety of chiral centers existing in the compound.


The offered compound is 1,2-difluoro-1,2-dimethylcyclopentane..

The structure is together follows:

*

From the structure, two chiral centers are existing in the molecule and plane of symmetry current is one isomer.

*

Now

The total number of stereo isomers is 2n−1\rm2^\rmn - 12n−1

The n=2Totalstereoisomers=(22−1)=3\beginarrayl\\\rmn\,\rm = \,\rm2\\\\\rmTotal stereotype isomers\,\rm = \,\left( \rm2^\rm2 - 1 \right)\\\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\rm = \,3\\\endarrayn=2Totalstereoisomers=(22−1)=3​

Therefore, the total number of stereo isomers is 3
