Organic Chemsitry: Stereochemistry

Identify the number of stereoisomers that are possible for a compound with the following constitution:

• 0

• 1

• 2

• 3

• 4

(a)   isomers have the same connectivity of atoms but differ in their spatial arrangement.

A compound with one chiral center will have one nonsuperimposable mirror image, called (a)  

A solution containing equal amounts of both enantiomers is called a (a)   mixture.

• same compound

• constitutional isomers

• diastereomers

• enantiomers
