Q
Q: Which of the following alkenes is most stable?
Solution: 2-Butene is more stable than 1-Butene due to hyperconjugation and steric hindrance.
Steps: 7
Step 1: Understand that alkenes are hydrocarbons with a double bond between carbon atoms.
Step 2: Know that stability of alkenes can be affected by factors like hyperconjugation and steric hindrance.
Step 3: Recognize that hyperconjugation is when adjacent carbon-hydrogen bonds can help stabilize the double bond.
Step 4: Identify that in 2-Butene, the double bond is between the second and third carbon, allowing for more hyperconjugation from surrounding carbon-hydrogen bonds.
Step 5: Understand that steric hindrance refers to the repulsion between atoms that are too close to each other, which can destabilize a molecule.
Step 6: Note that 1-Butene has more steric hindrance because the double bond is at the end of the carbon chain, making it less stable than 2-Butene.
Step 7: Conclude that 2-Butene is more stable than 1-Butene due to the effects of hyperconjugation and lower steric hindrance.
