To tackle this question, I’ll compare a nitrogen triple bond (N≡N) with a nitrogen double bond (N═N).
Option 1 says: higher, longer, greater. A higher bond order would be correct, but triple bonds are shorter, not longer, than double bonds, so this option misstates bond length and energy direction.
Option 2 says: lower, longer, greater.......Login to view full explanation登录即可查看完整答案
