Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring, adjacent to each other. The skeletal structure of one molecule is included to indicate the proper format; modify the X's on the given structure to create the first stereoisomer.
Homework Answers
Stereo isomers are isomers that have same molecular formula and constitutions around the atom but differ in their spatial arrangement of groups around the atom. Stereo isomers are mainly of two types (i) Enantiomers (ii) Diastereomers.
• Enantiomers: Enantiomers are stereo isomers, which are non-super imposable mirror images.
Isomers are mirror images but not super imposable.
• Diastereomers: Diastereomers are stereo isomers, which are non-super imposable non mirror images. Isomers are neither super imposable nor mirror images.
• The total number of stereo isomers for a compound is , where “n” is the number of chiral centers present in the compound.
• If plane of symmetry is present in the isomer, the total number of stereo isomers for a compound is , where “n” is the number of chiral centers present in the compound.
The given compound is 1,2-difluoro-1,2-dimethylcyclopentane..
The structure is as follows:
From the structure, two chiral centers are present in the molecule and plane of symmetry present is one isomer.
Now
The total number of stereo isomers is
The
Therefore, the total number of stereo isomers is 3
