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.
