本题目来源于试卷: Models of Bonding & Structure B.2 The Covalent Model，类别为 IB化学
[单选题]
Based on single, double, and triple bonds, which set of molecules is arranged in increasing order of their bond strength?
A. $H_2$<$N_2$<$O_2$
B. $H_2$<$O_2$<$N_2$
C. $O_2$<$H_2$<$N_2$
D. $N_2$<$O_2$<$H_2$
参考答案: B
本题详细解析:
$N_2$ has a triple bond,$O_2$ has a double bond, and $H_2$ only has a single bond.
The greater the number of shared pairs of electrons, the stronger the bond.
