[单选题]
Which shows the oxygen-to-oxygen bonds in order of increasing average bond enthalpy?
A. $O \equiv O<O=O<O−O$
B. $O−O<O \equiv O<O=O$
C. $O=O<O−O<O \equiv O$
D. $O−O<O=O<O \equiv O$
参考答案: D
本题详细解析:
Triple bonds are stronger than double bonds which are in turn stronger than single bonds. The greater the number of shared pairs of electrons, the stronger the bond and the greater the bond enthalpy.
