C21J Tutorial Paper #3

	1)  Arrange the first row transition metal elements in order of 
increasing abundance in the Earth's crust.

	2) Describe the extraction of Ti, Fe, Ni.

	3) Write the electronic configuration of Cu(I), Cr(II), Ti(III), 
Mn(II), Ni(III) and Co(II).

	4) What is the Jahn-Teller theorem and what are Jahn-Teller distortions?

	5) Write the electronic configurations for those ions expected to 
show Jahn-Teller distortions.

	6) Discuss the structure of VF5 in the solid, liquid and gas 
phases. 

	7) Give the structure and method of preparation of basic 
manganese(III) acetate.

	8) How is cobalt(III) fluoride prepared? Account for the lack of 
all other Co(III) halides.

	9) Why is it difficult to obtain Cu(I) species in aqueous solution?

	10) What happens when:
		a) solid potassium manganate(VII) is aded to conc. HCl?
		b) potassium manganate(VII) is used as an oxidant under 
strongly alkaline conditions?

	11) Many compounds of the type MX2  (where X=F,Cl,Br,I) adapt 
structures that can be described as: rutile, CdCl2 or CdI2. Describe 
these three structures, giving examples of first row transition metal 
halides that adapt them.
