The organic ligands 5- and 7- methyl-8-hydroxyquinoline have been synthesised and shown to form green, water soluble, 1:1 complexes with iron(III) and thus to possess the same composition as the complexes with 8-hydroxyquinoline and 2-methyl-8-hydroxyquinoline previously reported. Thermodynamic formation constants for the 1:1 complexes of 2-, 5- ,and 7-methyl-8-hydroxyquinoline with iron(III) have been determined -1 3 spectrophotometrically as 5.5. x 10¹⠴, 2.9 X 10¹⠵ and 3.6 x 10¹⠵ mole-¹ dm³ respectively at 25.0°C and I = 0.1M. When compared with the value 8.5 x lO¹⠴ for 8-hydroxyquinoline itself the results support the theory that methyl substitution affects the stability of these complexes by increasing the basicity of the nitrogen atom. The lesser stability of the 2-methyl complex, however, indicates an opposing steric effect of a bulky substituent in the 2-position. 2015-11-13T13:06:56Z 2015-11-13T13:06:56Z 1981 Master Thesis Masters MSc http://hdl.handle.net/11427/14967 eng application/pdf Department of Chemistry Faculty of Science University of Cape Town |
