Maharashtra HSC Chemistry study guide
Maharashtra HSC Chemistry · Work through your exam, one topic at a time.
The Maharashtra HSC Chemistry examination is the Class 12 chemistry paper set by the Maharashtra State Board of Secondary and Higher Secondary Education (MSBSHSE). It is taken by students completing higher secondary schooling in the science stream, and its marks are used for college admission, particularly for BSc, pharmacy, engineering and medical pathways where chemistry is a required subject. The Maharashtra HSC Chemistry study guide has 16 sections and about 3,932 words.
01Solid State
Solid State examines how particles pack into crystals and how that packing controls density, defects and physical properties. The board tests unit-cell types, packing efficiency, density calculations, point defects and band theory.
270 words, about 1 min02Solutions
Solutions tests how solute particles change vapour pressure, boiling point, freezing point and osmotic pressure, and how real solutions depart from ideal behaviour. Numerical questions on colligative properties and van't Hoff factor are common.
265 words, about 1 min03Ionic Equilibria
Ionic Equilibria covers acid-base strength, pH, buffers, hydrolysis and solubility product. The exam expects numerical pH and Ksp problems plus qualitative reasoning about common-ion effects.
264 words, about 1 min04Chemical Thermodynamics
Chemical Thermodynamics tests the first and second laws, enthalpy cycles, entropy, Gibbs energy and spontaneity. Expect sign-convention questions and calculations linking ΔG, ΔH, ΔS and K.
267 words, about 1 min05Electrochemistry
Electrochemistry covers galvanic and electrolytic cells, Nernst equation, conductance, Kohlrausch's law, Faraday's laws and commercial cells. Numerical EMF and conductivity questions are standard.
253 words, about 1 min06Chemical Kinetics
Chemical Kinetics tests rate expressions, order versus molecularity, integrated rate laws, half-life, Arrhenius behaviour and collision theory. First-order numericals dominate.
237 words, about 1 min07Elements of Groups 16, 17 and 18
Elements of Groups 16, 17 and 18 tests periodic trends, preparation and properties of oxygen, sulphur, halogens and noble gases, oxoacids and interhalogen compounds. Down Group 16: atomic radius increases, ionisation enthalpy decreases, metallic character increases; oxygen is a gas, sulphur a solid.
263 words, about 1 min08Transition and Inner Transition Elements
Transition and Inner Transition Elements tests electronic configurations, oxidation states, colour, magnetism, catalytic behaviour, alloys and the lanthanoid contraction. Transition elements have partially filled d orbitals in the atom or common ions; Zn, Cd and Hg are not typical transition metals.
257 words, about 1 min09Coordination Compounds
Coordination Compounds tests Werner's theory, IUPAC nomenclature, isomerism, valence bond theory, crystal field theory, stability and applications. Ligands are named alphabetically before the metal; anionic complexes end in -ate.
226 words, about 1 min10Halogen Derivatives
Halogen Derivatives tests classification, nucleophilic substitution (SN1 and SN2), elimination, Grignard reagents and named reactions such as Finkelstein and Swarts. SN1 proceeds via a carbocation, so reactivity is 3° 2° 1° methyl; it gives racemisation.
230 words, about 1 min11Alcohols, Phenols and Ethers
Alcohols, Phenols and Ethers tests classification, preparation, acidity, characteristic reactions and the Williamson synthesis. Alcohols: Lucas test (conc.
229 words, about 1 min12Aldehydes, Ketones and Carboxylic Acids
Aldehydes, Ketones and Carboxylic Acids tests nucleophilic addition, oxidation, named tests, aldol and Cannizzaro reactions, HVZ reaction and acidity. Aldehydes are more reactive than ketones toward nucleophilic addition because of less steric hindrance and less electron donation by alkyl groups.
232 words, about 1 min13Amines
Amines tests classification, preparation, basicity, Hinsberg and carbylamine tests, diazonium salt reactions and coupling. Basicity in water: aliphatic amines ammonia aromatic amines; aniline is weak because the lone pair is delocalised into the ring.
231 words, about 1 min14Biomolecules
Biomolecules tests carbohydrates, proteins, enzymes, vitamins and nucleic acids, with emphasis on classification, structure and biological function. Monosaccharides: glucose and fructose (C6H12O6).
241 words, about 1 min15Polymers
Polymers tests classification, addition and condensation polymerisation, monomer identification, rubber, molecular mass and biodegradable polymers. Addition polymers form without loss of a small molecule (polyethylene, PVC, polystyrene).
217 words, about 1 min16Green Chemistry and Nanochemistry
Green Chemistry and Nanochemistry tests the twelve principles of green chemistry, atom economy, green solvents and the synthesis, properties and applications of nanomaterials. Green chemistry designs processes that reduce or eliminate hazardous substances at source.
