1. Which of the following sets of quantum numbers (n, l, ml, ms) is not permissible for an electron in an atom?

   • 3, 2, -2, +1/2
   • 4, 0, 0, -1/2
   • 3, 3, 1, +1/2
   • 2, 1, -1, -1/2
   Show answer & explanation

   Answer: C. 3, 3, 1, +1/2

   The angular momentum quantum number (l) can only have integer values from 0 to n-1. Therefore, for n = 3, the maximum value l can have is 2. l cannot be equal to n.

2. According to the VSEPR theory, what is the molecular geometry and hybridization of the central atom in sulfur tetrafluoride (SF4)?

   • Tetrahedral, sp3
   • Seesaw, sp3d
   • Square planar, sp3d2
   • Trigonal bipyramidal, sp3d
   Show answer & explanation

   Answer: B. Seesaw, sp3d

   Sulfur in SF4 has 4 bonding pairs and 1 lone pair, giving a steric number of 5. This results in an sp3d hybridization and a seesaw molecular geometry because the lone pair occupies an equatorial position to minimize repulsion.

3. For the reaction A + B -> C, doubling the concentration of A quadruples the rate, while doubling the concentration of B has no effect on the rate. What is the overall order of the reaction?

   • 1
   • 2
   • 3
   • 0
   Show answer & explanation

   Answer: B. 2

   Since doubling [A] quadruples the rate, the reaction is second order with respect to A (2^2 = 4). Since doubling [B] has no effect, the reaction is zero order with respect to B. The overall reaction order is 2 + 0 = 2.

4. Consider the exothermic equilibrium reaction: N2(g) + 3H2(g) <=> 2NH3(g). Which of the following changes will increase the yield of ammonia (NH3) at equilibrium?

   • Increasing the temperature
   • Decreasing the total pressure of the system
   • Continuous removal of ammonia as it forms
   • Adding a catalyst to the system
   Show answer & explanation

   Answer: C. Continuous removal of ammonia as it forms

   According to Le Chatelier's principle, continuously removing the product (NH3) shifts the equilibrium position to the right, thereby increasing the overall yield of NH3.

5. What is the pH of a buffer solution prepared by mixing equal volumes of 0.2 M acetic acid (CH3COOH, Ka = 1.8 x 10^-5) and 0.1 M sodium acetate (CH3COONa)?

   • 4.74
   • 4.44
   • 5.04
   • 3.74
   Show answer & explanation

   Answer: B. 4.44

   Using the Henderson-Hasselbalch equation: pH = pKa + log([conjugate base]/[acid]). Here, pKa = -log(1.8 x 10^-5) = 4.74. Since equal volumes are mixed, the ratio of concentration remains 0.1/0.2 = 0.5. pH = 4.74 + log(0.5) = 4.74 - 0.30 = 4.44.

6. How many Faradays of electricity are required to deposit 21.6 g of silver (Ag) from a solution containing Ag+ ions? (Molar mass of Ag = 108 g/mol)

   • 0.1 F
   • 0.2 F
   • 0.5 F
   • 1.0 F
   Show answer & explanation

   Answer: B. 0.2 F

   Moles of Ag = 21.6 g / 108 g/mol = 0.2 mol. Since the reduction half-reaction is Ag+ + e- -> Ag, 1 mole of Ag requires 1 Faraday of electricity. Thus, 0.2 moles of Ag require 0.2 Faradays.

7. What is the correct IUPAC name for the organic compound: CH3-CH(CH3)-CH2-CH(OH)-CH3?

   • 2-methylpentan-4-ol
   • 4-methylpentan-2-ol
   • 2-hydroxy-4-methylpentane
   • 1,3-dimethylbutan-1-ol
   Show answer & explanation

   Answer: B. 4-methylpentan-2-ol

   The longest carbon chain contains 5 carbons (pentane). Numbering starts from the right end to give the principal functional group (-OH) the lowest possible number (carbon-2). The methyl substituent is then on carbon-4, giving the name 4-methylpentan-2-ol.

8. What is the correct number of significant figures in the result of the following mathematical calculation: (35.21 x 1.15) + 0.012?

   • 2
   • 3
   • 4
   • 5
   Show answer & explanation

   Answer: B. 3

   First, 35.21 x 1.15 = 40.4915. Since 1.15 has 3 significant figures, the multiplication result is rounded to 40.5 (3 sig figs, ending at the tenths place). Then, adding 40.5 + 0.012 = 40.512. For addition, the result is limited by the least precise decimal place (tenths place), yielding 40.5, which has 3 significant figures.
