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.

#### Details:
1. **Substance A**:
- Represents a molecule with the Lewis structure showing two carbon atoms double-bonded to an oxygen atom and bonded to hydrogen atoms.
2. **Substance B**:
- Represents the chemical formula for Carbon monoxide (CO).
3. **Substance C**:
- Represents the chemical formula for Oxygen (O₂).
4. **Substance D**:
- Represents the chemical formula for Aluminum oxide (Al₂O₃).
#### Instructions:
1. Examine each chemical or molecular structure carefully.
2. Understand the intermolecular forces present in each substance.
- Consider hydrogen bonding, ionic bonding, dipole-dipole interactions, and London dispersion forces.
3. Recall or research the typical boiling points of these substances.
4. Use the dropdown menu in the "Boiling Point" column to rank each substance appropriately.
**Note:** This exercise will help you understand how different molecular and chemical structures influence the boiling points of substances.
Good luck, and remember the key is understanding the types of bonds and forces at play in each substance!](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd290e29f-bf0a-4e13-893a-d0d06da948d8%2Fa00940f8-495a-402b-a39b-afadbf891f1d%2Fjddnvr_processed.jpeg&w=3840&q=75)
