3. Give the structure for each of the following species. a)o-ethyltoluene b)c/s-2,3-dichloro-2-.pentene c)isopropano丨 d) IF3 e)SO32—

【已刪除】4. The decomposition of N205 in the gas phase was studied at constant temperature: 2 N    O 5(G) → 4 NO2(g) + O2(g) the following results were collected: Using these data, verify that the rate law is first order in [N2O5], and calculate the rate constant.

5.逐句完整翻譯這段敘速成中文:Molecular structure is the three-dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color, .magnetism, and biological activity. The angles between bonds that an atom forms depend only weakly on the rest of molecule, i.e. they can be understood as approximately local and hence transferable properties.
