Summary
Highlights
Focus on Henry's Law (statement, equation, applications), Raoult's Law (statement, equation, graph), positive and negative deviation solutions, azeotropes (types, examples), osmosis, reverse osmosis, and osmotic pressure. Understand the differences between these concepts.
Master the SHE (Standard Hydrogen Electrode) explanation and diagram. Be proficient with the Nernst Equation for various cells, including the relationship with equilibrium constant (Kc) and standard Gibbs energy (ΔG°). Also, study Kohlrausch's Law (statement, applications), Faraday's Laws (first and second), lead storage battery (anode, cathode, electrolyte, reactions), fuel cells (especially H₂ fuel cell reactions), and corrosion.
Differentiate between Order and Molecularity. Understand First Order Reactions (equation, graph, half-life period derivation and definition) and Zero Order Reactions. Know about Pseudo-order reactions and their examples. Finally, study Collision Theory of chemical reactions, effective collision, and threshold energy.
Key topics include different oxidation states of transition metals and reasons for their variability. Magnetic properties (paramagnetic vs. diamagnetic based on unpaired electrons and the μ = √(n(n+2)) equation) are crucial. Interstitial compounds and their characteristics should also be studied. Pay special attention to the preparation of Potassium Dichromate and Potassium Permanganate, their structures, and Lanthanoid Contraction (definition and consequences).
This chapter is highly weighted. Understand ligands (types, including chelating ligands). Be capable of naming coordination compounds (IUPAC nomenclature). Master Isomerism, including structural isomers (ionization, solvate, coordination, linkage) and stereoisomers (geometrical, optical). Werner's Theory and its postulates are essential. Crystal Field Theory, particularly the splitting of d-orbitals in octahedral and tetrahedral fields, needs attention. Finally, understand Synergic Bonding (metal-carbonyl bond).
Focus on named reactions like Finkelstein reaction and Swarts reaction (halogen exchange). Understand Sandmeyer reaction and Gattermann reaction (from diazonium salts). SN1 and SN2 reactions (mechanisms and differences) are vital. Study Wurtz reaction, Fittig reaction, and Wurtz-Fittig reaction. Learn Saytzeff Rule and its examples. Be aware of why chloroform is stored in dark bottles.
Understand conversions like propene to propan-2-ol (acid-catalyzed hydration) and propene to propan-1-ol (hydroboration-oxidation). Study the preparation of phenol from Cumene. Know why phenols are more acidic than alcohols (resonance). Esterification and Aspirin preparation are important. Lukas Test (for distinguishing primary, secondary, and tertiary alcohols) is key. Learn reactions of phenol with dilute HNO₃ and concentrated HNO₃ (leading to picric acid formation). Kolbe's Reaction, Reimer-Tiemann Reaction, Williamson Synthesis, and the reaction of ethers with HX (especially HI) are also critical.
Preparations involving named reactions like Rosenmund Reduction, Stephen Reaction, Etard Reaction, and Gattermann-Koch Reaction are crucial. Understand why aldehydes are more reactive than ketones in nucleophilic addition reactions. Study examples of nucleophilic addition reactions (e.g., with HCN, ammonia derivatives). Familiarize yourself with Tollens' Test, Fehling's Test, and Haloform Test. Learn Aldol Condensation and Cannizzaro Reaction. Understand why carboxylic acids are more acidic than phenols and alcohols. Finally, study HVZ (Hell-Volhard-Zelinsky) Reaction.
Important named reactions include Gabriel Phthalimide Synthesis and Hofmann Bromamide Degradation Reaction. Understand the basicity of amines in aqueous and vapor phases for methylamines and ethylamines. Learn Carylamine Reaction (Isocyanide Test). Master Hinsberg Test for distinguishing primary, secondary, and tertiary amines. Study nitration of amines, noting the unique feature of ortho, para, and meta products. Finally, understand Diazotization (formation of diazonium halides) and Coupling Reactions.
Classify carbohydrates into monosaccharides, oligosaccharides, and polysaccharides with examples. Know why sucrose is called 'invert sugar'. Differentiate between essential and non-essential amino acids. Understand the zwitterion form of amino acids. Classify proteins (primary, secondary, tertiary, quaternary structures) and study protein denaturation. Finally, classify vitamins as water-soluble or fat-soluble and understand the reasons behind these classifications.
