Which of the following correctly describes the central atom hybridization, the number of lone pairs on the central atom, and the nature of bond lengths in a ClF ₃ molecule?

Options

  1. Asp ^3 d hybridization, 2 lone pairs, all bond lengths are equal
  2. Bsp ^3 d hybridization, 2 lone pairs, bond lengths are unequal
  3. Csp ^3 hybridization, 1 lone pair, bond lengths are unequal
  4. Dsp ^3 d ^2 hybridization, 3 lone pairs, all bond lengths are equal

Correct answer

B. sp ^3 d hybridization, 2 lone pairs, bond lengths are unequal

Step-by-step solution

For ClF ₃ : The number of valence electrons on the central atom Cl is 7 . The number of monovalent atoms ( F ) is 3 . Steric number = 7 + 3 2 = 5 . This corresponds to sp ^3 d hybridization. Since there are 3 bond pairs, the number of lone pairs on Cl is 5 - 3 = 2 . In sp ^3 d hybridization with 2 lone pairs, the lone pairs occupy equatorial positions to minimize repulsion, resulting in a T-shaped molecular geometry. Due to the unequal repulsion experienced by axial and equatorial bonds, the axial Cl - F bonds are
