Example 1 · difficulty 2/5
As predicted by VSEPR theory, the molecular shape of ClF₃ and the hybridisation of its central chlorine atom are, respectively:
- A. Trigonal bipyramidal, sp3d
- B. Bent (angular), sp³
- C. T-shaped, sp³d
- D. See-saw shaped, sp³d
Example 2 · difficulty 3/5
Applying molecular orbital theory to the superoxide ion O₂⁻ (17 electrons), its calculated bond order and magnetic behaviour are:
- A. Bond order 1.5, paramagnetic
- B. Bond order 2.5, paramagnetic
- C. Bond order 2.0, diamagnetic
- D. Bond order 1.0, diamagnetic
Example 3 · difficulty 3/5
NH₃ (μ ≈ 1.47 D) and NF₃ (μ ≈ 0.24 D) are both pyramidal molecules with sp³-hybridised nitrogen, yet their dipole moments differ enormously. The correct explanation is:
- A. NF₃ is planar triangular while NH₃ is pyramidal, so NF₃ achieves complete internal cancellation of bond dipoles
- B. The N–F bond is longer than the N–H bond, which lowers the product of effective charge and distance in NF₃
- C. Fluorine atoms pull the nitrogen lone pair entirely onto themselves, eliminating its contribution to the dipole
- D. In NH₃ the N–H bond moments point toward the lone-pair side and reinforce it, whereas in NF₃ the N–F bond moments point away and oppose the lone-pair moment
