Section-Wise HSC Chemistry Important Questions 2026

1-Mark Questions (MCQs & VSA)

These questions test your fundamental definitions and formula recall.

• Define: Unit cell, Isotonic solution, and Enthalpy of sublimation.

• What is the SI unit of molar conductivity?

• Name the metal nanoparticle used to remove $E. coli$ bacteria from water.

• Write the structure of $HClO_{3}$ and $HClO_{4}$.

• What are essential and non-essential amino acids?

2-Mark Questions (Short Answer I)

This section is heavy on "Distinguish Between" and "Give Reasons."

• Distinguish between ideal and non-ideal solutions.

• State and explain Kohlrausch’s Law of independent migration of ions.

• Explain the First Law of Thermodynamics and its mathematical form ($\Delta U = Q + W$).

• Give Reason: Carboxylic acids have higher boiling points than ethers of comparable mass.

• Define the term "Peptide Bond" and write the types of proteins based on molecular shape.

3-Mark Questions (Short Answer II)

Expect numericals and reaction mechanisms here.

• Explain the SN1 and SN2 mechanisms for the hydrolysis of alkyl halides.

• Calculate the standard enthalpy of combustion of $CH_{4}$ (numericals are highly repeated).

• Describe the Crystal Field Theory (CFT) for octahedral complexes.

• Explain the preparation of glucose from sucrose with chemical equations.

4-Mark Questions (Long Answer)

These often combine a derivation with a definition or a neat diagram.

• Derive the relation between $\Delta H$ and $\Delta U$ for a gaseous reaction.

• Draw a neat labeled diagram of the Standard Hydrogen Electrode (SHE) and mention its difficulties.

• Explain the formation of Polyethylene and its uses.

• Describe the working of a Lead Accumulator with cell reactions during charging and discharging.

Strategic CTA: Master Physics for 2026

While you prepare for Chemistry, don't ignore the technicalities of Physics. You can find the latest HSC Physics Paper Pattern 2026 to ensure your science stream preparation is balanced across all subjects.

How to Use These Questions Effectively

1. Textbook First: 95% of the Maharashtra Board paper comes from the Balbharati textbook. Use these important questions to highlight the "must-read" paragraphs in your book.

2. Maintain a Reaction Diary: Organic Chemistry (which accounts for ~25 marks) requires frequent revision of named reactions like Cannizzaro, Hoffmann-Bromamide, and Friedel-Crafts.

3. Numerical Logbook: Keep a list of formulas for Physical Chemistry. Chapters like Chemical Kinetics and Solutions have standard numerical patterns that repeat every year.

FAQs on HSC Chemistry Important Questions 2026

Q1: How many marks should I score in theory to pass HSC Chemistry 2026?

You need a minimum of 35% overall (Theory + Practical) to pass. However, aiming for 25+ out of 70 in theory is the safest way to ensure a clear pass regardless of practical marks.

Q2: Are HSC Chemistry important questions 2026 enough to score above 90%?

These questions cover the "repeated" and "most likely" topics. For a 90+ score, you must combine these with a thorough reading of the Balbharati textbook and solving at least 5 years of Previous Year Papers (PYQs).

Q3: Which section is the most difficult in the Chemistry paper?

Most students find Section C (3 marks) challenging because it combines theory with complex numerical calculations. Frequent practice with log tables is essential here.

Final Preparation Checklist

• Solved at least 5 years of PYQs (2021–2025).

• Practiced all diagrams (SHE, Fuel Cell, Dry Cell).

• Memorized the priority series for Organic IUPAC naming.

• Verified chapter weightage from the 2026 blueprint.

By prioritizing these HSC Chemistry important questions 2026, you aren't just studying hard—you’re studying smart. Good luck with your preparation!
