Sample questions with solutions
Q1 — easy
The VSEPR theory predicts that the geometry of NO₃⁻ is:
A. trigonal pyramidal
B. linear
C. trigonal planar ✓ Correct
D. tetrahedral
Solution: NO₃⁻ has 3 bonding pairs and no lone pairs. VSEPR predicts trigonal planar geometry with 120° bond angles.
Q2 — medium
The bond order of O₂⁻ is:
A. 2.5 ✓ Correct
B. 1.5
C. 2
D. 1
Solution: In O₂⁻, total electrons = 13. Bond order = (8-5)/2 = 1.5. Wait, let me recalculate: (bonding - antibonding)/2 = (8-5)/2 = 1.5. Actually for O₂⁻: order = 1.5
Q3 — medium
Which of the following has the maximum covalent character?
A. KF
B. NaF
C. LiF ✓ Correct
D. RbF
Solution: Covalent character increases with polarizing power of cation. Li⁺ has the smallest size and highest charge density, giving LiF maximum covalent character.
