Draw the optically active stereoisomer(s) of 1,3-cyclopentanediol.

             The three possible stereoisomers of 1,3-cyclopentanediol are as follow,

                  i) (1S,3R)-1,3-Cyclopentanediol

                  ii) (1R,3R)-1,3-Cyclopentanediol

                  iii)  (1S,3S)-1,3-Cyclopentanediol

Structures of all three compounds are attached below.

Stereoisomers: Also known as spatial isomers are those isomers which have same molecular formula and structural formula but the groups about the chiral center occupy different orientation in space.

Enantiomers: These are stereoisomers of each other which are non-identical mirror-images of each other.

Diastereomers: These are stereoisomers which are not mirror images of each other.

Meso Compounds: These are those isomers which are superimposible on its mirror image.

the answer is either b or c
