01
General chemistry priorities
- Stoichiometry, gases, solutions, and concentration
- Thermodynamics, kinetics, and equilibrium
- Acids, bases, buffers, and solubility
- Atomic structure, periodic trends, bonding, and intermolecular forces
- Electrochemistry and laboratory reasoning
02
Organic chemistry priorities
- Structure, stability, acidity, and basicity
- Stereochemistry and spectroscopy
- Substitution, elimination, and addition patterns
- Carbonyl chemistry and synthesis logic
- Laboratory techniques and structural evaluation
03
A calculation workflow
- Write the target unit before selecting an equation.
- Estimate the sign and rough magnitude.
- Carry units through the setup.
- Check whether the answer matches the physical trend.
