The hyperconjugative stabilities of tert-butyl cation and 2-butene,...
The hyperconjugative stabilities of tert-butyl cation and 2-butene, respectively, due to
Options
- Aσ \to \text{p} (empty) and σ \to {π}^{*} electron delocalisations.
- Bσ \to {σ}^{*} and σ \to π electron delocalisations.
- Cσ \to \text{p} (filled) and σ \to π electron delocalisations.
- D\text{p (filled)} \to {σ}^{*} and σ \to {π}^{*} electron delocalisations.
Correct answer
A. σ \to \text{p} (empty) and σ \to {π}^{*} electron delocalisations.
Step-by-step solution
In tert-butyl cation, carbon bearing charge has one vacant p orbital hence it is (empty) conjugation or Hyperconjugation.
In 2-butene hyperconjugation between and bond.
