Please fill in the blank ! In part B, the difference is that the molecules have more than one atom with two or more attached neighbors. As molecules become larger and more complex, VSEPR theory does not attempt to create names for the overall geometries that result. Instead, we continue to consider the geometry about one central atom at a time. By giving the arrangement about each such atom in the larger structure, we can generate enough information to develop an overall picture. Thus, in your report for part B, you should determine which atoms have more than one bound neighbor, then repeat the procedure for part A. When deciding whether the molecules in part B are polar or nonpolar, focus on the molecule as a whole, not the geometry about a single atom. If the molecule is polar, draw a dipole arrow on your sketch indicating polarity.

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.

Transcribed Image Text:Part B. MODELS WITH MORE THAN ONE CENTRAL ATOM
In part B, the difference is that the molecules have more than one atom with two or more attached
neighbors. As molecules become larger and more complex, VSEPR theory does not attempt to
create names for the overall geometries that result. Instead, we continue to consider the geometry
about one central atom at a time. By giving the arrangement about each such atom in the larger
structure, we can generate enough information to develop an overall picture. Thus, in your report for
part B, you should determine which atoms have more than one bound neighbor, then repeat the
procedure for part A. When deciding whether the molecules in part B are polar or nonpolar, foCus
on the molecule as a whole, not the geometry about a single atom. If the molecule is polar, draw a
dipole arrow on your sketch indicating polarity.
