Chemistry · Electronic displacement in a covalent bond: Inductive effect, electromeric effect, resonance and hyperconjugation
Which of the following is maximum stable?
Which of the following is maximum stable?
- A. Conjugated alkadiene \( \left(C H_{2}=C H-C H=C H_{2}\right) \)
- B. Isolated alkadiene \( \left(C H_{2}=C H-C H_{2}-C H=C H_{2}\right) \)
- C. cumulated alkadiene \( \left(C H_{2}=C=C H_{2}\right) \)
- D. All are equal
Step-by-step solution
Conjugated dienes have overlapping p-orbitals allowing resonance stabilization, making them more stable than isolated or cumulated dienes. Cumulated dienes are strained and less stable, while isolated dienes lack conjugation.
