Which is the most stable hydrocarbon?
- cis-2-butene
- isobutylene
- trans-2-butene
- 1-butene
Explanation
The most stable hydrocarbon among the given options is trans-2-butene.
Stability in alkenes:
- The stability of alkenes is primarily determined by the degree of substitution at the double bond.
- More substituted alkenes are generally more stable.
Trans vs. Cis Isomers:
- In the case of 2-butene, the trans isomer is more stable than the cis isomer.
- This is because in the trans configuration, the alkyl groups on either side of the double bond are oriented away from each other, minimizing steric hindrance.
- In the cis configuration, the alkyl groups are on the same side, leading to steric repulsion and less stability.
