The Valence Shell Electron Pair Repulsion Vsepr Theory

Shape of cuprammonium, ion is square planar.

Answer (c) tetrahedral

The molecular orbital (MO) configuration for can be determined by filling the molecular orbitals starting from the lowest energy. The energy levels for the and orbitals will follow this order: For , each carbon atom contributes 4 electrons, giving a total of 8 electrons. According to the MO theory for molecules with even numbers of electrons, the configuration is:

To determine the number of bond pairs and lone pairs in a molecule, we need to look at its Lewis structure and VSEPR theory:
- NH (Ammonia) has 3 bond pairs and 1 lone pair on nitrogen.
- SO (Sulfur dioxide) has 2 bond pairs and 1 lone pair on sulfur.
- ClF (Chlorine trifluoride) has 3 bond pairs and 2 lone pairs on chlorine.
- SF (Sulfur tetrafluoride) has 4 bond pairs and 1 lone pair on sulfur.
- H O (Water) has 2 bond pairs and 2 lone pairs on oxygen.
Thus, the molecule with 3 bond pairs and 2 lone pairs is ClF (C).
