B) Draw the Lewis Structure and for each bond in the molecule, indicate if the bond is polar or non-polar. Use the +-> notation to show the direction of polarity (arrow pointing to 8-) for all polar bonds. For non- polar bonds, put NP in a small circle next to that bond. HS
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.
Can you please check my work. (the structure is in the picture)
A) What is the Chemical Formula and number of unshared electron PAIRS in the skeletal structure below?
the chemical formula should be C6H15S2O3N and the number of unshared electron pairs is 6.
B) Draw the Lewis Structure and for each bond in the molecule, indicate if the bond is polar or non-polar.
Use the +-------> notation to show the direction of polarity (arrow pointing to δ-) for all polar bonds. For non-
polar bonds, put NP in a small circle next to that bond.
The only polar bonds should be between NH (point towards N), OH (point towards O), and SO (point towards S)
