### VSEPR Theory and Molecular GeometryBelow is an example table summarizing the Valence Shell Electron Pair Repulsion (VSEPR) theory aspects of the methane molecule (CH₄):| Molecule or Molecular Ion | Lewis Structure | Valence Shell Electron Pairs | Bonding Electron Pairs | Nonbonding Electron Pairs | VSEPR Formula | Approx. Bond Angle | Geometric Shape ||----------------------------|-----------------|------------------------------|------------------------|---------------------------|---------------|-------------------|-----------------|| 1. CH₄ | H | 4 | 4 | 0 | AX₄ | 109.5° | tetrahedral || | .. | | | | | | || | H:C:H | | | | | | || | .. | | | | | | || | H | | | | | | |**Figure Explanation:**- **Lewis Structure:** This depicts the arrangement of atoms and electrons in the molecule. For CH₄, the carbon atom (C) is at the center with four hydrogen atoms (H) attached via single bonds.- **Valence Shell Electron Pairs:** Number of electron pairs in the valence shell of the central atom, including both bonding and nonbonding pairs.- **Bonding Electron Pairs:** Number of electron pairs that are participating in bonds.- **Nonbonding Electron Pairs:** Number of lone pairs of electrons on the central atom.- **VSEPR Formula:** The notation AX₄ indicates that the central atom (A) has four bonding pairs (X) and no lone pairs.- **Approximate Bond Angle:** The angle between adjacent bonds in the molecule. For CH₄, this is approximately 109.5°.- **Geometric Shape:** The spatial arrangement of the atoms. For CH₄, this arrangement is tetrahedral.### Practice Problem**3.** Complete the table (as outlined above) for the following molecules/molecular ions.
