MDCAT Chemistry QUESTION #4348
Question 1
In propene, the $\pi$-bond is formed by sideway overlap of:
  • s-orbitals
  • p-orbitals✔️
  • $sp^3$ hybrid orbitals
  • $sp^2$ hybrid orbitals
Correct Answer Explanation
In propene ($CH_3CH=CH_2$), the double bond carbons are $sp^2$ hybridized. The $\pi$-bond is formed by the lateral (sideway) overlap of unhybridized $p$-orbitals perpendicular to the molecular plane.
