Which statement regarding a pi bond between two carbon atoms is correct? A) The region of high electron density lies along the bond axis connecting the nuclei of the two atoms. B) The bond can be described by the overlap of sp hybrid orbitals from each atom. C) The bond can be described by the overlap of sp² hybrid orbitals from each atom. D) The bond can be described by the overlap of p atomic orbitals from each atom. E) The bond can be described by the overlap of a p atomic orbital from one atom with an sp² hybrid orbital from the other atom.

Question

Quizplus · Accepted Answer

The pi bond between two carbon atoms is formed by the overlap of p atomic orbitals from each atom. Choice A describes a sigma bond, not a pi bond. Choice B describes a sp hybrid orbital, which is involved in a sigma bond. Choice C describes a hybrid orbital that does not exist. Choice E describes a hybrid orbital involving both p and s orbitals, which is not involved in a pi bond.
