1. Multiple choice: why is it uncommon to draw lewis diagrams for ionic compounds?

A.) Lewis diagrams can only illustrate covalent bonding
B.) ionic compounds cannot be represented by Lewis diagrams
C.) ionic compounds involve electron transfer not electron sharing
d.) formulas for ionic compounds are predictable and understandable based on ion charges

2. What is a major source of organic molecules?

3. What type of industrial plant (factory) is used to separate mixtures of organic compounds?

Thanks:)

1. I don't know that I believe it is uncommon to draw Lewis diagrams of ionic compounds. If we go with that assumption, however, I would go with d.

2. food? oil?

3. Doesn't it all depend upon what kind of mixture we have? For example, we separate oil (petroleum) at refineries. We might separate drugs at a pharmaceutical plant. etc.

1. C) ionic compounds involve electron transfer not electron sharing... but also because they're camera shy and prefer to stay out of the limelight!

2. Well, I'm no gardener but I hear that plants are a pretty major source of organic molecules. Just watch out for those sneaky ones that like to play hide and seek!

3. Ah, the industrial plant that separates mixtures of organic compounds? That would be the "Divide & Conquer" plant! It has a knack for breaking up mixtures and keeping things nice and organized. It's like a celebrity personal assistant for molecules!

1. The correct answer is C.) Ionic compounds involve electron transfer, not electron sharing.

Explanation: Lewis diagrams are used to show the arrangement of atoms and valence electrons in covalent compounds, where electrons are shared between atoms to form bonds. In ionic compounds, on the other hand, atoms transfer electrons to achieve a stable electron configuration. The resulting ions are held together by electrostatic forces, rather than covalent bonds. Therefore, using Lewis diagrams to depict ionic compounds would not accurately represent the way the electrons are involved in the bonding.

2. The primary source of organic molecules is living organisms, such as plants and animals.

Explanation: Organic molecules are based on carbon atoms, which are the building blocks of life. Organic molecules can be found in various forms, including carbohydrates, lipids, proteins, and nucleic acids, which are crucial for the functioning of living organisms. They are synthesized through biochemical pathways in living organisms, making them a major source of organic molecules.

3. An industrial plant (factory) used to separate mixtures of organic compounds is called a distillation plant or a distillation column.

Explanation: Distillation is a widely used technique for separating mixtures based on differences in their boiling points. In the context of organic compounds, distillation can be used to separate a mixture of compounds with different boiling points. The mixture is heated, and the compounds with lower boiling points vaporize first, while those with higher boiling points remain as liquid or solid. The vapor is then cooled and condensed back into a liquid, allowing for the separation and collection of individual compounds based on their boiling points. This process can be efficiently performed on a large scale in industrial distillation plants, also known as distillation columns.
