Question: 33

3. A carbon atom participates in one double bond. As such, this carbon contains orbitals with:

  • A. hybridization between the s-orbital and one p-orbital.
  • B. hybridization between the s-orbital and two p-orbitals.
  • C. hybridization between the s-orbital and three p-orbitals.
  • D. no hybridization between the s-orbital and p-orbitals.

Correct Answer: B

Explanation:

In a carbon with one double bond, sp2 hybridization occurs—that is, one s-orbital hybridizes with two p-orbitals to form three sp2-hybridized orbitals. The third p-orbital of the carbon atom remains unhybridized and takes part in the formation of the π bond of the double bond.
