Answer: Benzyl carbocation.
- A Vinyl carbocation
- B Primary carbocation
- C Secondary carbocation
- D Benzyl carbocation
Correct answer: D. Benzyl carbocation
Explanation: Benzyl carbocation is highly stabilised by resonance with the aromatic 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.
