A)pi, sigma
B)sigma, pi
C)pi, pi
D)sigma, sigma
E)ionic, sigma

Question

Quizplus · Accepted Answer

Sigma bonds involve the overlap of orbitals directly between two atoms, so electrons in sigma bonds remain localized between those two atoms. Pi bonds involve the overlap of orbitals above and below the plane of the atoms, so electrons in pi bonds can become delocalized between more than two atoms. The correct option is (B) sigma, pi.
