4. (a) When 62.8 g of an alkyl halide derivative D were
dissolved in 106 g of 1-butanol, the boiling point of the mixture
was 120.9 ℃. Deduce and draw the structure of D, given that there
are 2.5 times the number of chlorine atoms than carbon atoms in the
compound. (12 marks) (b) One way in which the stoichiometry of a
complex ion can be determined is by measuring the color intensities
of solutions containing different proportions of the ligand and
metal ion. In one such experiment, the maximum color intensity was
observed when 5.2 cm3 of a 1 x 10-3 M manganese ion solution and
1.56 cm3 of a 1 x 10-2 M solution of ethylenediamine were mixed.
Given that one mole of a compound containing the complex ion from
this mixture produces three moles of silver chloride when the
compound reacts with excess silver nitrate, show whether the
compound is diamagnetic or paramagnetic. (8 marks)
