[单选题]
The molecule $O_2$ contains one σ and one π bond. How do p orbitals in the O atoms overlap to produce the π bond?
A. End-to-end overlap results in high electron density along the bond axis
B. Sideways overlap results in high electron density along the bond axis
C. End-to-end overlap results in high electron density above and below the bond axis
D. Sideways overlap results in high electron density above and below the bond axis
参考答案: D
本题详细解析:
The student must recall the appearance of a π bond and the way in which it is formed. This information is stated clearly in the syllabus, so the question is categorized as easy.
Option A describes the formation of a σ bond.
