Answer: Diastereomers.
- A Enantiomers
- B Diastereomers
- C Optical isomers
- D Conformers
Correct answer: B. Diastereomers
Explanation: Diastereomers are stereoisomers that are not mirror images.
Geometric (cis-trans) isomers of 1,2-dichloroethene differ only in the relative arrangement of groups across the rigid C=C double bond.
Concept context
General Organic Chemistry covers the rules behind all organic reactions. Covers inductive effect, resonance, hyperconjugation, types of reactions (substitution, addition, elimination), and isomerism including optical and geometric forms.
