d block elements(AL9)

係 inorg chem裡面，d-block elements 係好重要o架。係今個syllabus只係改咗少少，取消咗d-block ions colour 嘅reason。新加嘅就有complex formation裡面嘅bidentate ligands (H2NCH2CH2NH2 同埋 C2O42-) 同埋 multidentate ligands (EDTA)。如果今年考complex formation，睇o黎都會考e d 新ligands。

同學仔要知道ligands嘅 relative strength：monodentate multidentate ligands (EDTA)。但係其實佢哋都係舊瓶新酒，e d內容係兩代前嘅syllabus都有o架啦。

同學仔，其實d block elements有好多值得做嘅pastpaper,不過化學友都盡力精選左幾條出o黎，希望精益求精啦:

1. 1992 Paper II 4a

2. 1996 Paper II 6b

3. 1998 paperII 8a

4. 1999 paper II 2d
