Answer: Resonance.
- A Inductive effect
- B Hyperconjugation
- C Resonance
- D Electromeric effect
Correct answer: C. Resonance
Explanation: Benzene is stabilised by resonance because its pi electrons are delocalised over the ring.
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.
