IB Topic or IA
Further detail
Would need to be linked with other data to use for an IA.
Solubility of salts based on anion / cation combination.
Length of C chain and London forces
Could be useful in structure-spectra correlations.
Comprehensive spectral database for organic compounds, contains NMR (1H, 13C), IR, mass spec, and more.
Thermochemistry related IA
Thermochemistry data, IR, mass spectrum data.
Comparison of the physical data like boiling point and melting point to the bonding
Physical data: solubility, boiling point, melting point, vapor pressure, heat of combustion and vaporisation.
IA / Topic 4 (Bonding)
How do the position of neighbouring atoms affect bond angles, bond lengths, positions free molecules and ions, and orientation of free molecules.
Molecular modeling program for theoretical studies of systems of any complexity.
IA / Topic 15 (Energetics)
15.2 Comparison of experimental and calculated data, structure, entropy related topics
Both experimental and calculated data, detailed data of geometry and entropy
IA / Topic 15 (Energetics)
15.2 Entropy (S) refers to the distribution of available energy among the particles. The more ways the energy can be distributed the higher the entropy. Gibbs free energy (G) relates the energy that can be obtained from a chemical reaction to the change in enthalpy (ΔH), change in entropy (ΔS), and absolute temperature (T). Entropy of gas>liquid>solid.
IA = Calculation of Gibbs Free energy / entropy and compare theoretical v actual
IA / Topic 16 (Kinetics)
Atmospheric chemical kinetic data
Rate of formation of radicals / rate of breakdown of ozone
Periodicity topic 3
3.2 Vertical and horizontal trends in the periodic table exist for atomic radius, ionic radius, ionization energy, electron affinity and electronegativity
Trends and patterns in melting / boiling points radius of atom / ion in a group or period
Topic 5 (Colorimetry)
5.1 (Enthalpy changes of combustion (∆Hc°) and formation (∆Hf°) should be covered
How do changing various factors (eg, carbon chain length) affect enthalpies of combustion?
