Electronic Structures of CF4, SF4, and XeF4
The central atoms in CF4, SF4, and XeF4 are carbon (C), sulfur (S), and xenon (Xe), respectively. Let's analyze the electronic structures of these molecules to determine the correct option.
CF4:
Carbon is in group 4 of the periodic table, and it has a valence electron configuration of 2s^2 2p^2. In CF4, carbon forms four covalent bonds with four fluorine atoms. Each fluorine atom contributes one electron to the bonding, forming four sigma bonds with carbon. The carbon atom shares its four valence electrons with the four fluorine atoms, resulting in a complete octet around carbon. Therefore, there are no lone pairs of electrons on the central carbon atom in CF4.
SF4:
Sulfur is in group 6 of the periodic table, and it has a valence electron configuration of 3s^2 3p^4. In SF4, sulfur forms four covalent bonds with four fluorine atoms. Similar to CF4, each fluorine atom contributes one electron to the bonding, forming four sigma bonds with sulfur. However, sulfur has two lone pairs of electrons in its valence shell. These lone pairs occupy two of the four available hybrid orbitals, resulting in a distorted tetrahedral geometry around the sulfur atom. Therefore, there is one lone pair of electrons on the central sulfur atom in SF4.
XeF4:
Xenon is in group 18 of the periodic table, and it has a valence electron configuration of 5s^2 5p^6. In XeF4, xenon forms four covalent bonds with four fluorine atoms. Each fluorine atom contributes one electron to the bonding, forming four sigma bonds with xenon. Xenon has six lone pairs of electrons in its valence shell. These lone pairs occupy six of the eight available hybrid orbitals, resulting in a square planar geometry around the xenon atom. Therefore, there are two lone pairs of electrons on the central xenon atom in XeF4.
Conclusion:
Based on the analysis of the electronic structures of CF4, SF4, and XeF4, the correct option is b) 0, 1, and 2 lone pairs of electrons, respectively.
