1.以 Be2分子為例 試比較定域化電子模型理論 及分子軌域模型之不同
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. 試比較CO和O2 CS和S2中何者比較不穩定 試用C和O原子行程拍鍵的能力來加以解釋

關於MO跟LE理論 可以請各位高手完整的比較解釋嘛?
看原文版的課本 一整個沒有辦法翻的很通順 挫折很大 = ="
還望各位多多幫忙了
