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.

**Detailed Explanation of Lewis Structure:**
The image presents the Lewis structure for iodine trifluoride (IF₃). In this diagram, the iodine (I) atom is at the center with three fluorine (F) atoms bonded to it. Each fluorine atom has three lone pairs of electrons around it, illustrated by pairs of dots (:). The iodine atom also has two lone pairs of electrons.
Students are asked to determine the hybridization on the central atom (iodine), the electron domain geometry, the molecular geometry, whether the molecule is polar or non-polar, and the bond angle between the fluorine atoms around the iodine.
**Problems for Students:**
1. Identify the hybridization state of the iodine atom in IF₃.
2. Determine the electron domain geometry around the iodine atom.
3. Predict the molecular geometry of IF₃.
4. Address whether IF₃ is a polar or non-polar molecule.
5. Calculate the F-I-F bond angle in the IF₃ molecule.
