Q.
How many stereoisomers are possible for dichlorocyclobutane?
Hydrocarbons
Solution:
1, 3-Dichlorocyclobutane can exist in cis and trans forms, trans-1, 2-Dichlorocyclobutane can exist in (+) - and (-) - forms. However, cis-1, 2 Dichlorocyclobutane has a plane of symmetry and hence it can exist as meso isomer.
