,Section A - Atomic Structure AND Periodicity
Q1.
Which set of quantum numbers (n, , m, ms) is permissible for an electron in a
ground-state atom?
A. (3, 3, 0, +½) B. (2, 1, 1, +½)
C. (4, 2, +3, ½) D. (1, 0, +1, +½)
Correct: B - (2, 1, 1, +½)
Rationale:For n = 2, ! can be 0 or 1; m! ranges from "! to +! so "1 is allowed, and ms = +½
is valid. The other sets violate n1, |m| , or m = 0 when = 0.
Why the other answers are wrong:
A. = 3 is not allowed when n = 3 ( must be n1 = 2).
C. m = +3 exceeds the maximum |m| = = 2.
D. For = 0, m must be 0, not +1.

Q2.
A 25.0 mL sample of 0.100 M HCl is titrated with 0.100 M NaOH. What is the pH at the
equivalence point?
A. 7.00 B. 5.00
C. 8.72 D. 12.00
Correct: A - 7.00
Rationale:HCl is a strong acid and NaOH a strong base; at the equivalence point the solution
contains only NaCl and water, so pH = 7.00 at 25 °C. The other values would apply to weak
acid/base titrations or regions before/after equivalence.
Why the other answers are wrong:
B. pH 5 corresponds to a partially neutralized strong acid, before equivalence.
C. pH 8.72 would arise from a weak acid-strong base titration with a basic conjugate.
D. pH 12 corresponds to excess strong base well past the equivalence point.

Q3.
Which molecule is polar overall despite containing polar bonds?
Page 3
, Section A - Atomic Structure AND Periodicity
A. CO B. CCl
C. HO D. BF
Correct: C - HO
Rationale:H ‚O has a bent geometry (VSEPR) so the two O–H bond dipoles do not cancel,
giving a net dipole moment. CO, CCl, and BF are linear, tetrahedral, and trigonal planar,
respectively, and their bond dipoles cancel by symmetry.
Why the other answers are wrong:
A. CO is linear; equal and opposite C=O dipoles cancel.
B. CCl is tetrahedral; the four C-Cl dipoles cancel.
D. BF is trigonal planar; the three B-F dipoles cancel.
Reference: Brown, T.L. et al. (2023). Chemistry: The Central Science, 15th Ed., Ch. 9
Q4.
At constant temperature, a 2.0 L sample of gas at 1.0 atm is compressed to 0.50 L. What is
the new pressure?
A. 0.25 atm B. 2.0 atm
C. 4.0 atm D. 8.0 atm
Correct: C - 4.0 atm
Rationale:Boyle's law (P •V • = P ‚V ‚) gives P ‚ = (1.0 atm × 2.0 L)/0.50 L = 4.0 atm. Pressure
and volume are inversely proportional at constant T.
Why the other answers are wrong:
A. 0.25 atm would result from multiplying instead of applying inverse proportionality.
B. 2.0 atm corresponds to a volume ratio of 0.5, not 0.25.
D. 8.0 atm would require a fourfold volume decrease from a larger initial pressure.

Q5.
For the reaction N(g) + 3H(g) -> 2NH(g), H° = 92 kJ/mol. Which change shifts the
equilibrium toward more NH?
A. Increasing temperature B. Decreasing pressure
C. Removing N D. Increasing pressure
Correct: D - Increasing pressure
