1.
  a particle is confined to a one-dimension box of length 300 pm ,for∣∣∣
                                                                     ∣⊥∣
                                                                       ∣ 3
  the particle is most likely to be found at

  A.75pm  B.100pm  C.125pm  D.175pm  E.250pm

2.
  in pure liquid ammonia ,the equilibrium concentration of both [NH4+] and

  [NH2-] are 3x10^-14M at 25。C. Which of the following equation holds for

  liquid ammonia solutions at 25。C ?

  A.pNH4+ +pNH2-=13.5  B.pNH4+ = pNH2- =13.5  C.pNH4+ =27.0

  D.pNH4+ = 27.0－ pNH2- E.pNH4+ =log[pNH4]

我選 BD

3.
  which of the following is optically active?

  A.2-chloropane  B.3-chloropentane  C.3,3-dichlorohexane

  D.[CoCl6]3- E.[Co(en)3]3+

optically 是四邊取代基都不同?!

4.
  which of the following ligands might give linkage isomers?

  1.NO2- 2.SCN- 3.H2N-H2C-CH2-NH2

  (A)1 2 (B)1 3 (C)2 3 (D)none (E)1 2 3


這四題麻煩各位大大幫忙囉!!謝謝
ps:轉胞加油:)

→ pterome:4  linkage A  3是箝合  應該沒有
→ pterome:1  我也想知道答案
→ com11080:可以解是一下嗎?!不懂= =
→ pterome:linkage指的是  Ｍ＋接ＮＯ2  接N  OR  ONO  接Ｏ 你問這?
→ pterome:就= =  我怎麼表達  就  可不可以換接點? 同個配機
→ pterome:三的話?  舊址有Ｎ鈷對電子可以接點   好難描述我要說得
