Mumbai University TYBSc Chemistry: Past Paper Patterns (2018–2022)

Paper Structure Overview

TYBSc Chemistry typically has two papers (I & II), each with Section A (short answers) and Section B (descriptive). Topics rotate across physical, inorganic, organic, and analytical chemistry.

Recurring Themes by Year

2018

• Paper I: Electronic config, NaCl formula, water boiling point; photosynthesis, ionic vs. covalent, states of matter.
• Paper II: C₆H₁₂O₆ ID, alcohol functional group, methane combustion; fermentation, saturated vs. unsaturated, enzyme roles.

2019

• Paper I: Electronic config, K₂SO₄ formula, gold melting point; cellular respiration, acids/bases, reaction types.
• Paper II: C₂H₅OH ID, aldehyde group, ethene hydrogenation; polymerization, aromatic vs. aliphatic, vitamin roles.

2020

• Paper I: Electronic config, CaCO₃ formula, water density; protein synthesis, metals/non-metals, thermodynamics laws.
• Paper II: CH₃COOH ID, carboxylic acid group, benzene chlorination; saponification, polymers vs. plastics, carbohydrate roles.

2021

• Paper I: Electronic config, H₂SO₄ formula, water specific heat; DNA replication, covalent vs. ionic, states of matter (5?).
• Paper II: C₆H₆ ID, alkene group, propane combustion; distillation, alkanes vs. alkenes, lipid roles.

2022

• Paper I: Electronic config, NaOH formula, neutral pH; enzyme catalysis, endo/exothermic, nuclear reactions.
• Paper II: C₅H₁₂O ID, ether group, butane chlorination; cracking, alcohol classification, protein roles.

Study Strategy

1. Master electronic configurations (annual in Section A).
2. Memorize functional group identification (alcohol, aldehyde, carboxylic acid, alkene, ether).
3. Practice balanced equations for combustion, hydrogenation, halogenation.
4. Prepare 5–6 key descriptive answers (processes: photosynthesis, respiration, fermentation, polymerization, DNA replication, distillation, cracking).
5. Review comparisons: bonding types, hydrocarbon classes, alcohol degrees, thermodynamic concepts.
