, Physical Chemistry — Final Recall
• Mole calculations: n=m/M and particle count N=nNA. Track units at every step.
• Thermodynamics: ∆G=∆H−T∆S. At constant T,P, ∆G<0 indicates spontaneity.
• Equilibrium: distinguish K from reaction quotient Q; compare Q with K to predict direction.
• Electrochemistry: Ecell=Ecathode−Eanode; ∆G=−nFE. Reduction at cathode, oxidation at anode.
• Kinetics: order comes from rate law; first-order t1/2=0.693/k.
• Solutions: identify molarity vs molality and remember that colligative effects depend on particle number.
Inorganic Chemistry — Final Recall
• Across a period, radius generally decreases while effective nuclear attraction increases.
• Use VSEPR for shape and electron-pair repulsion ideas; do not confuse electron geometry with molecular shape.
• Coordination number counts directly bonded donor atoms; denticity counts donor sites of a ligand.
• Track oxidation numbers systematically; total oxidation number in a neutral compound is zero.
• Revise characteristic trends and exceptions in p-block and d/f-block chemistry.
Organic Chemistry — Final Recall
• Electron effects: inductive, resonance, hyperconjugation and steric effects control stability and reactivity.
• Alkenes/alkynes commonly undergo electrophilic additions; aromatic rings favor substitution that retains aromaticity.
• Primary alcohol oxidation: alcohol → aldehyde → carboxylic acid under progressively stronger oxidation.
• Carbonyl compounds undergo nucleophilic addition; aldehydes are generally more readily oxidized than ketones.
• Amine basicity depends on electron availability, solvation and molecular environment.
• Biomolecules: know functional groups, linkage types and major biological roles.
