Answer: 120 degrees.
- A 90 degrees
- B 109.5 degrees
- C 120 degrees
- D 180 degrees
Correct answer: C. 120 degrees
Explanation: sp<sup>2</sup> hybridisation produces trigonal planar geometry with 120 degree bond angles.
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.
