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-chloropropane 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
