Sample AFU Common Entrance Exam Practice Questions

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

1In Bohr's model of the hydrogen atom, what is the condition for the quantization of angular momentum of an electron orbiting in the nth stationary state?

A.mvr = nh / π

B.mvr = nh / (2π)

C.mvr = 2nh / π

D.mvr = nh / (4π)

Explanation: According to Bohr's second postulate of the atomic model, an electron can revolve only in those non-radiating stable orbits where its orbital angular momentum (L = mvr) is an integral multiple of h / (2π), which is expressed mathematically as mvr = nh / (2π), where n = 1, 2, 3, ... is the principal quantum number.

2What is the oxidation state of chromium in potassium dichromate (K2Cr2O7)?

A.+6

B.+3

C.+7

D.+4

Explanation: In K2Cr2O7, potassium (K) has an oxidation state of +1 and oxygen (O) has an oxidation state of -2. Setting up the algebraic equation for the neutral molecule: 2(+1) + 2(Cr) + 7(-2) = 0 yields +2 + 2(Cr) - 14 = 0, giving 2(Cr) = +12, so each Cr atom has an oxidation state of +6.

3How many molecules of oxygen gas are present in 16 grams of O2 at standard temperature and pressure (STP)?

A.6.022 × 10²³ molecules

B.1.204 × 10²⁴ molecules

C.3.011 × 10²³ molecules

D.1.505 × 10²³ molecules

Explanation: The molar mass of molecular oxygen (O2) is 32 g/mol. A mass of 16 g corresponds to 16 / 32 = 0.5 moles of O2. Since 1 mole contains Avogadro's number of molecules (6.022 × 10²³), 0.5 moles contains 0.5 × 6.022 × 10²³ = 3.011 × 10²³ molecules.

4Which characteristic functional group distinguishes aliphatic aldehydes from other carbonyl-containing compounds?

A.-COOH group

B.-OH group

C.>C=O bonded to two alkyl groups

D.-CHO group

Explanation: Aldehydes possess a carbonyl group (>C=O) bonded to at least one hydrogen atom, forming the terminal formyl group (-CHO). Ketones contain a carbonyl group bonded to two carbon atoms, while carboxylic acids have -COOH.

5What is the pH of a 0.001 M aqueous hydrochloric acid (HCl) solution at 25 °C?

A.3

B.1

C.11

D.4

Explanation: Hydrochloric acid is a strong monoprotic acid that dissociates completely in water: HCl → H⁺ + Cl⁻. Therefore, [H⁺] = 0.001 M = 10⁻³ M. The pH is calculated as pH = -log10[H⁺] = -log10(10⁻³) = 3.

6Which neutral chemical element has the ground-state electronic configuration 1s² 2s² 2p⁶ 3s² 3p⁴?

A.Phosphorus (P, Z = 15)

B.Sulfur (S, Z = 16)

C.Chlorine (Cl, Z = 17)

D.Silicon (Si, Z = 14)

Explanation: Adding the electrons: 2 + 2 + 6 + 2 + 4 = 16 electrons. The neutral atom with atomic number Z = 16 is sulfur (S), located in group 16 (chalcogens) and period 3 of the periodic table.

7Under conditions of constant temperature and pressure, which thermodynamic criterion guarantees that a chemical reaction will proceed spontaneously?

A.ΔG > 0 (positive change in Gibbs free energy)

B.ΔG = 0 (zero change in Gibbs free energy)

C.ΔG < 0 (negative change in Gibbs free energy)

D.ΔH < 0 regardless of entropy change

Explanation: According to the second law of thermodynamics, a chemical process at constant temperature and pressure is spontaneous in the forward direction if and only if the change in Gibbs free energy is negative (ΔG = ΔH - TΔS < 0). When ΔG = 0, the system is at equilibrium, and when ΔG > 0, the forward reaction is non-spontaneous.

8Choose the correct word to complete the sentence: 'The farmer could not decide _______ to sow wheat or mustard after the rice harvest.'

A.whether

B.weather

C.either

D.that

Explanation: 'Whether' introduces a choice between alternatives and can be followed by a to-infinitive: 'decide whether to sow wheat or mustard'. 'Weather' is a noun for atmospheric conditions, so it is a spelling confusion here.

9Which of the following ores is industrially concentrated using the froth flotation process?

A.Bauxite (Al2O3·2H2O)

B.Haematite (Fe2O3)

C.Calamine (ZnCO3)

D.Copper pyrites (CuFeS2)

Explanation: The froth flotation process is specifically used for the concentration of low-grade sulfide ores based on the differential wetting characteristics of ore particles and gangue. Sulfide ore particles, such as copper pyrites (CuFeS2), are preferentially wetted by pine oil and rise with the froth, while gangue particles are wetted by water and settle at the bottom.

10If the half-life (t1/2) of a first-order chemical reaction is 20 minutes, what fraction of the original reactant will remain unreacted after 60 minutes?

A.25%

B.12.5%

C.6.25%

D.50%

Explanation: The total elapsed time is 60 minutes. The number of half-lives elapsed is n = t / t1/2 = 60 / 20 = 3 half-lives. For a first-order reaction, the remaining fraction is [A] / [A]0 = (1/2)ⁿ = (1/2)³ = 1/8 = 0.125, which corresponds to 12.5%.
