GAMSAT - Chemistry

I have nearly finished my revision for the Chemistry section of GAMSAT (I think)
I've been steadily making my way through a list of recommended topics and making sure I understand them.

Although since I've been going through the practice questions, the chemistry questions seem so much harder than what I have been revising! (cry)

Here is a list of the topics I have covered for Chemistry, and I haven't really done "proper" Chemistry since AS Level and I've basically forgotten it all and I HATE it :(

Atoms

• Periodic trends and the nature of atoms
• Understand common elements
• Balance equations

Bonding 

• Different types and properties of bonds
• Electronegativity and polarity of molecules 
• Effect of electron withdrawing groups
• Electron orbitals and quantum numbering 

Equilibrium 

• Le Chateliers principle
• Effect of heat, catalysts and concentration on rate of reaction

Gases

• Ideal gas laws 

Solutions 

• Apply Ksp values
• Understand how chemical properties effect solubility 

Colligative Properties

• Boiling point elevation and freezing point depression
• Raoults Law 
• Heat capacity and specific heat

Thermodynamics

• Laws of thermodynamics
• Gibbs free energy, entropy, enthalpy
• Predict wether a reaction will be spontaneous
• Will a reaction be exo/endo

Acids and Bases

• Pka values
• conjugate pairs
• Does a molecule act as a base or a pair depending on it's structure
• General acid base stuff!
• Oxidation and reduction 
• Apply E values

Organic Chemistry 

• IUPAC naming conventions
• Draw molecular structures from name 
• Isomers
• Chirality
• Alkanes, Alkenes, Alkynes
• Alcohols, Esters, Carboxylic Acids, Amines, Ketones, Aldehydes etc
• Properties and effects of major functional groups
