The carbon-carbon σ bond in ethylene, H₂C-CH₂, results from the overlap of __________.

Question

Quizplus · Accepted Answer

The carbon atoms in ethylene are sp2 hybridized, which means they have three hybrid orbitals in a trigonal planar arrangement and one unhybridized p orbital perpendicular to the plane. The σ bond between the carbon atoms is formed from the overlap of the two sp2 hybrid orbitals. Therefore, choice C, which corresponds to sp2² hybrid orbitals, is the correct choice. Choices A, B, and D are not correct because they describe hybridizations or orbitals that are not involved in the formation of the σ bond in ethylene. Choice E is also not correct because p orbitals are involved in the formation of the π bond in ethylene, not the σ bond.
