How can you model simple hydrocarbons

Hydrocarbons are made of hydrogen and carbon atoms. Recall that carbon has four valence electrons and it can form four covalent bonds. 

Use a molecular model kit to build a structure with two carbon atoms connected by a single bond. 

Place hydrogen atoms in all of the unoccupied positions on your model so that each carbon atom has a total of four bonds. 

Repeat Steps 2-3 for models based on three, four, and five carbon atoms each. Be sure that each carbon atom is attached to a maximum of two other carbon atoms. 

Make a table listing the number of carbon and hydrogen atoms in each structure.
