Hydrocarbon Models & Naming Practice

Atoms bond with other atoms in specific ways. In this lab, you will construct the molecules indicated in the
boxes below using the molecular model kits. Remember – carbon forms four bonds. These bonds can be single,
double or triple. Oxygen and nitrogen can also form single and double bonds. Use the correct colors for the
different elements: black = carbon, white = hydrogen, red = oxygen, blue = nitrogen.
After you have constructed the molecules, draw the structure of the molecule in the space provided. Draw the
molecule to the shape you see with the models.

Hydrocarbon Review
1. The name for a hydrocarbon generally consists of two parts. The first part indicates the number of carbon
atoms in the chain. Fill in the blanks.
1 C atom –
6 C atoms –
2 C atoms–
7 C atoms –
3 C atoms-
8 C atoms –
4 C atoms –
9 C atoms–
5 C atoms –
10 C atoms –
2. The second part of the name of a hydrocarbon is the same as that of its series. When you know the series to
which a hydrocarbon belongs, you have other information available: Fill in the blanks.
