According to the VSEPR theory , the arrangement of lone pairs of the central atom in a molecule containing a total of three lone pairs and two bond pairs is​

Answer 1

According to VSEPR theory, the arrangement of lone pairs of the central atom in a molecule containing a total of three lone pairs and two bond pairs is sp3d hybridized with triangular bipyramidal geometry and Linear shape

What is VSEPR theory?

• It stands for Valence-shell Electron-pair repulsion theory.
• The VSEPR model can predict the structure of nearly any molecule or polyatomic ion in which the central atom is a nonmetal, as well as the structures of many molecules and polyatomic ions with a central metal atom.
• Each group around the central atom is designated as a bonding pair (BP) or lone (nonbonding) pair (LP) which can determine the shape and geometry of a molecule.
• In this question, the hybridization is given by 2 bond pairs + 3 lone pairs=5 (sp3d hybridized).
• Let us take an example of I3⁻ molecule:-

1. There are five electron groups about the central atom in I3−, two bonding pairs and three lone pairs. To minimize repulsions, the groups are directed to the corners of a trigonal bipyramid.  
2. With three nuclei and three lone pairs of electrons, the molecular geometry of I3− is linear.
