10.2(b)
- Studies limited to complexes of - Formation of transition
Fe(II), Fe(III), Co(II) and Cu(II) metal complexes as with
with the following ligands: ….
monodentate ligands (H2O,
NH3, Cl– and CN–),
bidentate ligands
(N2NCH2CH2NH2 and
C2O42–-) and multidentate
ligands (EDTA).

Fundamentals of Organic Chemistry
New Features
11.1 Bonding and structure
11.5 Organic acids and organic bases
11.6 Reaction mechanism
Chemistry of Organic Compounds
- Link up the class of compounds with their
major type of reactions
- Place emphasis on the mechanistic aspects
- Reduce the number of reactions
- Add a separated chapter of redox reactions
- Introduce structure
determination by modern
spectroscopic methods
(IR and MS)
Chemistry in Action
- A completely new section to replace
Chemistry and Society
- Link up Chemistry with STS elements
(Polymers and Drugs)
e.g. effect of structure on properties of polymers
key stages of drug development
-
With contemporary topics such as Green
Chemistry
