The total number of dichlorinated isomers (including stereoisomers) obtained upon the dichlorination of cyclopentane is

Step-by-step solution

Dichlorination of cyclopentane produces three structural isomers: 1,1-dichlorocyclopentane, 1,2-dichlorocyclopentane, and 1,3-dichlorocyclopentane. 1. 1,1-dichlorocyclopentane has no chiral centers and does not show stereoisomerism. (1 isomer) 2. 1,2-dichlorocyclopentane has two chiral centers. The cis-isomer has a plane of symmetry and is a meso compound (1 isomer). The trans-isomer lacks a plane of symmetry and exists as a pair of enantiomers (2 isomers). Total = 3 isomers. 3. 1,3-dichlorocyclopentane also has tw
