Arrangement of Lone Pair and Bond Pairs in XY2 Molecule

The given molecule XY2 contains two s bonds, two p bonds, and one lone pair of electrons in the valence shell of X. The arrangement of lone pair as well as bond pairs can be determined by applying the VSEPR (Valence Shell Electron Pair Repulsion) theory.

VSEPR Theory

According to VSEPR theory, the electron pairs in the valence shell of an atom repel each other and try to stay as far apart as possible to minimize repulsion. The shape of a molecule is determined by the number of electron pairs around the central atom and their arrangement in space.

Application of VSEPR Theory

In the given molecule XY2, X has two bond pairs and one lone pair of electrons. Therefore, the total number of electron pairs around X is three. Based on this information, we can predict the arrangement of lone pair and bond pairs as follows:

- Step 1: Determine the electron pair geometry

The electron pair geometry is the spatial arrangement of all electron pairs (bond pairs as well as lone pairs) around the central atom. In the given molecule XY2, X has three electron pairs. Therefore, the electron pair geometry is trigonal planar.

- Step 2: Determine the molecular geometry

The molecular geometry is the spatial arrangement of only the bond pairs around the central atom. In the given molecule XY2, X has two bond pairs. The lone pair of electrons will occupy a position opposite to the bond pairs to minimize repulsion. Therefore, the molecular geometry is bent or V-shaped.

Conclusion

Based on the VSEPR theory, the arrangement of lone pair and bond pairs in the XY2 molecule is trigonal planar for the electron pair geometry and bent or V-shaped for the molecular geometry. Therefore, the correct answer is option C.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Band theory of solid:Consider that the Si or Ge crystal contains N atoms. Electrons of each atom will have discrete energies in different orbits. The electron energy will be same if all the atoms are isolated, i.e., separated from each other by a large distance. However, in a crystal, the atoms are close to each other (2 Å to 3 Å) and therefore the electrons interact with each other and also with the neighbouring atomic cores. The overlap (or interaction) will be more felt by the electrons in the outermost orbit while the inner orbit or core electron energies may remain unaffected. Therefore, for understanding electron energies in Si or Ge crystal, we need to consider the changes in the energies of the electrons in the outermost orbit only. For Si, the outermost orbit is the third orbit (n = 3), while for Ge it is the fourth orbit (n = 4). The number of electrons in the outermost orbit is 4 (2s and 2p electrons). Hence, the total number of outer electrons in the crystal is 4N. The maximum possible number of outer electrons in the orbit is 8 (2s + 6p electrons). So, out of the 4N electrons, 2N electrons are in the 2N s-states (orbital quantum number l = 0) and 2N electrons are in the available 6N p-states. Obviously, some p-electron states are empty. This is the case of well separated or isolated atoms.Q. In a crystal, the distance between two atoms is
