Which of the following pairs of species are iso-structural?

Options

  1. ABF₃ and ClF₃
  2. BNH₃ and NO₃^-
  3. CCH₄ and SF₄
  4. DXeF₂ and I₃^-

Correct answer

D. XeF₂ and I₃^-

Step-by-step solution

Iso-structural species have the same shape. BF₃ has 3 bond pairs and 0 lone pairs on Boron, resulting in a trigonal planar shape. ClF₃ has 3 bond pairs and 2 lone pairs on Chlorine, resulting in a T-shape. NH₃ has 3 bond pairs and 1 lone pair on Nitrogen, resulting in a trigonal pyramidal shape. NO₃^- has 3 bond regions and 0 lone pairs on Nitrogen, resulting in a trigonal planar shape. CH₄ has 4 bond pairs and 0 lone pairs on Carbon, resulting in a tetrahedral shape. SF₄ has 4 bond pairs and 1 lone pair on Sulfur,
