What role does fluorine play in making fluorosulfuric acid (FSO3H) stronger than sulfuric acid?
What role does fluorine play in making fluorosulfuric acid (FSO3H) stronger than sulfuric acid?
Fluorine is more electronegative than oxygen, pulling electrons away from the O-H bond and increasing the partial positive charge on hydrogen.

Study Notes
Orbital Interactions
- Orbital interactions can be categorized as σ-bonding, σ-antibonding, π-bonding, π-antibonding, or non-bonding.
Aqueous Permanganate and Oxalate Reaction
- Aqueous permanganate ([MnO₄⁻]) reacts with aqueous oxalate ([C₂O₄]²⁻) under acidic conditions to produce gaseous carbon dioxide (CO₂) and aqueous manganese (II) ion (Mn²⁺).
- The balanced chemical equation is: 16H⁺(aq) + 2MnO₄⁻(aq) + 5[C₂O₄]²⁻(aq) → 10CO₂(g) + 2Mn²⁺(aq) + 8H₂O(l).
Concentration of Ions
- Solutions with higher concentrations of ions have greater numbers of ions in solution.
- For example, 1.50 M Al(NO₃)₃ has the greatest concentration of ions (6.00M) compared to the other solutions.
Crystal Field Theory
- Decreasing the oxidation state of a metal center does not lead to a greater crystal field splitting. This is because it leads to a decrease in metal-ligand bonding strength.
- Decreasing the electronegativity of a ligand's binding atom decreases a ligand's ability to donate electron density to the metal center, thus leading to a decrease in crystal field splitting.
- An increase in crystal field splitting makes the probability that a metal center will reside in a low spin electron configuration greater.
- The d₂² and dₓ²-y² orbitals participate in bonding, while the remaining d-orbitals are non-bonding in an octahedral arrangement.
Coordination Complexes
- Complex 1 is most likely to reside in a low-spin configuration.
- Complex 3 will have the greatest crystal field splitting.
- Complex 2 is most likely to absorb the lowest energy visible light. (E.g., red).
- A complex that absorbs 600 nm light appears blue.
Gas Containers
- Assuming ideal behavior, Container A (He) has the greatest pressure of gas.
- Assuming ideal behavior, Container C (NH₃) has the greatest density of gas.
- Assuming real behavior, Container C (NH₃) has the lowest pressure of gas.
- Assuming real behavior, all containers have the same greatest volume of available space.
Chemical Reactions
- Various chemical reactions and their classifications (precipitation, acid/base, redox) are described.
Boiling Point
- From a given set of structures, the compound with the highest boiling point should be selected.
Oxidation Numbers
- Oxidation numbers are assigned to the central atoms of given molecules.
Surface Tension, Viscosity etc analysis
- 1,4-dioxane is more miscible with hexane.
