What type of isomerism do these models represent? 18. Geometric Isomers of CICH = CHCI (1,2-dichloroethene) Perspective drawings of both isomers: a. Make two models that have different spatial arrangement of the substitutions (the two Cl atoms) across the double bond. b. Draw the perspective formulae for the two isomers and label them with their correct designations. c. What type of isomerism do these represent?
