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.

Choose the "Playground" option to complete this modeling activity: You can drag and drop molecules to the screen and put them
together then click the 3D button to see a model like the one we would make in the classroom. Make sure to check the ball & stick model
mode in 3D viewer- this is important for seeing the bonds (sticks)!
1. Build the molecule (you can see different element choices by clicking the dots at the bottom of the screen)
2. Draw the Lewis structure.
3. Count the number of bonds and lone pairs on the central atom (lone pairs are not shown on the models only on your Lewis Structure)
4. Use bond and lone pair information to determine the shape of the molecule (linear, bent, trigonal planar, tetrahedral)
4. Calculate the polarity of each different bond by subtracting atom electronegativities.
5. Use the bond types and shape to determine if the molecule is polar or nonpolar
