Identify the shape of IF ₅ molecule from the following options.

Options

  1. ATrigonal bipyramidal
  2. BSquare planar
  3. CHexagonal
  4. DSquare pyramidal

Correct answer

D. Square pyramidal

Step-by-step solution

The central atom is Iodine (I), which has 7 valence electrons. It forms 5 single bonds with 5 Fluorine (F) atoms. Number of bond pairs = 5 Number of lone pairs = 7 - 5 2 = 1 Total number of electron pairs = 5 + 1 = 6 The hybridization of the central atom is sp^3d^2 , which corresponds to an octahedral electron geometry. Due to the presence of 5 bond pairs and 1 lone pair, the molecular shape is square pyramidal. Answer: Square pyramidal
