Answer: Dihedral angle 0 degrees.
- A Dihedral angle 60 degrees
- B Dihedral angle 180 degrees
- C Dihedral angle 0 degrees
- D Dihedral angle 120 degrees
Correct answer: C. Dihedral angle 0 degrees
Explanation: In eclipsed conformation, bonds align directly behind each other with 0 degree dihedral angle.
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.
