Work in groups of 2 or 3. Each person is to answer questions on a separate sheet of paper to be handed in. Answer in full sentences please.
Follow along with the interactive website shown by the teacher.
1.
Create Propane with your molecular model kit
2.

7.
Why does each structural isomer have its own unique name?
8.
In a line angle formula, each line represents a carboncarbon bond. Each end of a line, as well as the intersection of lines, represents a carbon atom. All hydrogen atoms are understood. Knowing that carbon always forms four bonds in organic compounds, explain how to determine the number of hydrogen atoms bonded to each carbon in a line-angle formula.
