思路分析
To tackle this question, I’ll compare NO2+ and NO2− in terms of bond order, bond length, and bond energy.
Option 1: 'a lower, a longer, a greater' would imply NO2+ has a weaker, longer, and stronger bond than NO2−, which contradicts the general trend that removing electrons from a molecule (forming cation) often incr......Login to view full explanation登录即可查看完整答案
