Carbon disulfide is a colorless, volatile, highly flammable liquid with a very unpleasant smell that is used as a solvent in some laboratory applications. The formula for carbon disulfide is CS2. Formal charges can be used to decide whether its connectivity is more likely to be C–S–S or S–C–S. Part1: Add any nonzero formal charges to the atoms as applicable for the Lewis structure shown with connectivity C–S–S. All valence electrons have been included, and this structure follows the octet rule. If formal charges are equal to zero, they should not be included. Part2: Add any nonzero formal charges to the atoms as applicable for the Lewis structure shown with connectivity C–S–S. All valence electrons have been included. If formal charges are equal to zero, they should not be included. (This structure is a resonance form of the structure in Part 1.) part 3: Add any nonzero formal charges to the atoms as applicable for the Lewis structure shown with connectivity S–C–S. All valence electrons have been included, and this structure follows the octet rule. If formal charges are equal to zero, they should not be included.
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.
