- each carbon atom forms a total of 4 covalent bonds.
5- Organic molecules - A molecule that contains only carbon and any of the following: hydrogen, oxygen, nitrogen, sulfur, and/or phosphorous
6- Inorganic molecules - non-carbon-based molecule such as O2, NH# ammonia or H2O
7- hydrocarbons- organic molecules that are composed of only carbon and hydrogen. Many hydrocarbons are important fuels (Methane CH4) is one of the most abundant hydrocarbons in natural gas. Fat molecules in your body contain hydrocarbons.
8- four functional groups? Hydroxyl group, Carbonyl group, Carboxyl group, Amino Group
9- Hydrophilic - attracts water molecules. These type of molecules tend to become surrounded by H2O molecules in an aqueous environment
10- Hydrophobic - Avoids water molecules
11- Monomers - Small molecular unit that is the building block of a larger molecule
