Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.

**Question Analysis:**
1. **How many electron groups are around the central sulfur atom?**
- **Note:** One "electron group" refers to one lone pair, one single bond, one double bond, or one triple bond.
- **Student Input:** [Student is expected to input a number]
2. **What phrase best describes the arrangement of these electron groups around the central sulfur atom?**
- **Options Provided:**
- Linear
- Bent
- T-shaped
- Trigonal planar
- Trigonal pyramidal
- Square planar
- Square pyramidal
- Tetrahedral
- Sawhorse
- Trigonal bipyramidal
- Octahedral
- **Dropdown Selection:** Bent (selected by the student)
**Educational Explanation:**
The sulfur trifluoride anion (\(SF_3^-\)) involves understanding the VSEPR (Valence Shell Electron Pair Repulsion) theory, which predicts the shape of a molecule based on electron group repulsions. Here, students determine how many electron groups surround the central sulfur atom by considering lone pairs and bonds as separate groups. After identifying the number of electron groups, students then select the best description of the molecular geometry from a list of options.
