What is the Structural formula of [Ni(NH3)6]2+?
Explain structural isomerism and the different types that exist (i.e. chain, positional and functional group). Give at least two examples of each type, including structural formulae and photographs of 3D models to illustrate more clearly what structural isomerism is. Compare different structural isomers which have the same molecular formula, considering the difference in physical or chemical properties.
Construct and analyse an example of each of the following reaction mechanism types:
• Addition e.g. aldehyde or ketone with HCN
• Substitution e.g. halogenoalkane with ethanolic NaOH
• Addition-elimination e.g. aldehyde or ketone with 2,4-dintriophenylhydrazine
This section must explore and interpret the similarities and differences between each of the four mechanisms.
