1.以 Be2分子为例 试比较定域化电子模型理论 及分子轨域模型之不同
2.compare and contrast the MO model with the LE model
3.schoose the stable substance and explain why the other compound is unstable
a.NF5 or PF5 b.NF3 or NBr3
4.discuss the importance of C-C and Si-Si bond strengths and of π bonding
to the properties of carbon and silicon
5.Distinguish between isomerism and resonance
6.explain and define the following statement:
a. the structure of silica is SiO4 instead of Sio2 but the discrete CO2
is a stable molecule
b. inert pair effect
c. amphoteric species
d. water-softening by ion exchange
e. metalloids or semimetals
7. 试比较CO和O2 CS和S2中何者比较不稳定 试用C和O原子行程拍键的能力来加以解释

关於MO跟LE理论 可以请各位高手完整的比较解释嘛?
看原文版的课本 一整个没有办法翻的很通顺 挫折很大 = ="
还望各位多多帮忙了
