Suppose that you want to determine whether a ligand X is a
weak-field or strong-field ligand. Would you synthesize an
octahedral complex of ligand X with Cr3+ or Co3+? Explain your
reasoning and illustrate with relevant appropriate crystal-field
energy diagrams for each complex.
PdCl42- has a weak field ligand, Cl-, so it should has a
tetrahedral structure, but the experiment show that PdCl42- has a
square planar structure. EXPLAIN why PdCl42-has a square planar
structure and give me other six metal that have this behaviour.
For each of the following, indicate if the species is a strong
or weak acid. If it is a weak acid, write the hydrolysis reaction
and the Ka expression.
HF
HI
HNO2
H2SO3
HClO3
HClO4
H2SO4
HClO
For each of the substances in below classify it as a strong or
weak electrolyte and state whether
it exists in solution as molecules, ions, or a mixture of both
molecules and
ions.
a) hypochlorous acid
b) strontium hydroxide
c) perchloric acid
d) butanoic acid
1.
a) For each of the three versions of market efficiency (weak,
semi-strong, and strong) give an example of a stock price movement
(can be real or hypothetical) that would NOT be consistent with
that version of efficiency.
b) What sorts of factors might limit the ability of rational
investors to take advantage of any pricing errors that result from
the actions of “behavioral investors”?
: carbonyl(CO) is strong field ligand so [Ni(CO)4] should have
square planar shape but by the experiment [Ni(CO)4] is
tetrahedral.Explain this statement.
