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

Question

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:)

Answer 1

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.
