Sample Maharashtra HSC Chemistry Practice Questions

Try these sample questions to review concepts for the Maharashtra HSC Chemistry exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A solid in which constituent particles are arranged in a long-range, repeating three-dimensional pattern is called a:
A.Amorphous solid
B.Crystalline solid
C.Supercooled liquid only
D.Plasma
Explanation: Crystalline solids have long-range order with a definite crystal lattice and sharp melting points. Amorphous solids lack long-range order and soften over a temperature range.
2How many atoms are effectively present in a face-centred cubic (FCC) unit cell?
A.1
B.2
C.4
D.8
Explanation: In FCC: 8 corner atoms × 1/8 = 1 and 6 face-centred atoms × 1/2 = 3, total Z = 4 atoms per unit cell.
3The packing efficiency of a body-centred cubic (BCC) crystal structure is closest to:
A.52%
B.68%
C.74%
D.100%
Explanation: BCC packing efficiency is 68% (exactly (π√3)/8). Simple cubic is ~52% and FCC/HCP ~74%.
4An octahedral void in a close-packed structure is surrounded by how many spheres?
A.3
B.4
C.6
D.8
Explanation: An octahedral void is formed by six spheres arranged at the vertices of an octahedron. A tetrahedral void is surrounded by four spheres.
5The density of a crystal is given by ρ = (Z × M) / (a³ × N_A), where a is the edge length. If Z doubles and a remains constant, density:
A.Halves
B.Doubles
C.Remains unchanged
D.Becomes four times
Explanation: Density is directly proportional to Z when M, a, and N_A are fixed. Doubling Z doubles ρ.
6A Schottky defect in an ionic crystal involves:
A.An ion missing from its lattice site with no charge balance consideration
B.Equal numbers of cation and anion vacancies maintaining electrical neutrality
C.Only interstitial cations with no vacancies
D.Only freons trapped in voids
Explanation: A Schottky defect is a pair (or stoichiometric set) of cation and anion vacancies so the crystal remains electrically neutral. Frenkel defects involve dislocation of an ion to an interstitial site.
7A metal crystallises in FCC with edge length a = 400 pm and molar mass M = 60 g mol⁻¹. Approximate density (N_A = 6.0 × 10²³) is closest to:
A.2.5 g cm⁻³
B.6.25 g cm⁻³
C.12.5 g cm⁻³
D.1.0 g cm⁻³
Explanation: ρ = ZM/(a³ N_A); Z = 4; a = 4.00 × 10⁻⁸ cm; a³ = 6.4 × 10⁻²³ cm³; ρ = (4 × 60)/(6.4 × 10⁻²³ × 6.0 × 10²³) = 240/38.4 ≈ 6.25 g cm⁻³.
8Molality (m) is defined as:
A.Moles of solute per litre of solution
B.Moles of solute per kilogram of solvent
C.Grams of solute per 100 mL of solution
D.Moles of solvent per kilogram of solute
Explanation: Molality is moles of solute per kilogram of solvent. Unlike molarity, it is independent of temperature because mass does not change with T.
9According to Raoult’s law for an ideal solution of a non-volatile solute, the vapour pressure of the solvent is:
A.Independent of mole fraction
B.Equal to the pure solvent vapour pressure times solvent mole fraction
C.Equal to the pure solute vapour pressure times solute mole fraction
D.Always equal to atmospheric pressure
Explanation: Raoult’s law: p_solvent = p°_solvent × x_solvent for a solution of non-volatile solute (solute contributes negligible vapour).
10Which colligative property depends on the number of solute particles, not their chemical identity?
A.Colour of the solution only
B.Elevation of boiling point
C.Density of pure solvent only
D.Atomic number of solute
Explanation: Colligative properties — relative lowering of vapour pressure, elevation of boiling point, depression of freezing point, and osmotic pressure — depend on the number of solute particles.

Maharashtra HSC Chemistry: Suggested Study Strategy

1Build chapter-wise formula sheets for solid-state density, colligative properties, Nernst equation, integrated rate laws, and thermodynamic relations (ΔG = ΔH − TΔS).
2Drill organic mechanism maps: SN1 vs SN2, nucleophilic addition to carbonyls, and identification tests (Tollens, Fehling, Hinsberg, Lucas).
3Practise numericals with units: molarity/molality, conductivity, Faraday electrolysis, half-life, and packing efficiency.
4Link inorganic trends (oxidation states, colour, magnetism, lanthanoid contraction) to coordination compound isomerism and CFT.
5After MCQ concept checks, write full short/long/numerical answers under ~3-hour timing using MSBSHSE past papers and Balbharati exercises; keep practical record current.
