The bonds are very strong, they are not extremely reactive under ordinary conditions, and carbon can form up to four single covalent bonds.
What are the three characteristics of carbon bonds that make them unique?
Nanotubes are made of hexagons of carbon atoms that form a hollow tube. They are very small and thin (about 10,000 times smaller than the diameter of a human hair), but they are very strong, up to 10 to 1000 times stronger than steel.
What is unique about a nanotube, the newly discovered allotrope of carbon?
They are classified based on the bonding between carbon atoms. Alkanes have single bonds, alkenes have one or more double bonds, and alkynes have at least one triple bond.
How are hydrocarbons classified?
Functional groups are involved in chemical reactions. They are responsible for how an organic compound reacts and help determine its properties.
What role do functional groups play in the behavior of organic compounds?
They are similar in that they are both alcohols and they both have the same molecular formula. But their atoms are arranged differently, giving them different chemical and physical properties. These two molecules are isomers.
How are 1-butanol and isobutyl alcohol similar? How are they different?
The carbon atoms in a saturated hydrocarbon form four single covalent bonds with other atoms. Not all of the carbon atoms in an unsaturated hydrocarbon have four single covalent bonds.
Compare saturated hydrocarbons to unsaturated hydrocarbons.
The four ways include a chemical formula, a structural formula, a skeletal structure, and a space-filling model.
What are the four ways to represent an organic molecule?
Hydrogen is shown only when it is part of the functional group.
When is hydrogen shown in a skeletal structure?
A substitution reaction is a reaction where one or more atoms replace another atom or group of atoms. An addition reaction is a reaction in which an atom or molecule is added to an unsaturated molecule, increasing the saturation of the molecule.
How is a substitution reaction different from an addition reaction?
Vegetable oil is converted to a solid form through the process of hydrogenation. Hydrogenation is a simple addition reaction where hydrogen gas is passed through the oil, adding hydrogen atoms to the unsaturated molecule.
How is vegetable oil converted into solid margarine?
Polyethylene is made from the monomer ethene. The ethene monomers are joined together to form larger molecules through addition reactions.
How is polyethylene made?
Two molecules combine in a condensation reaction, usually resulting in the formation of a water molecule. An elimination reaction occurs when a simple molecule is removed from adjacent carbon atoms on the same organic molecule.
How is a condensation reaction different from an elimination reaction?
Nylon is produced from a condensation reaction between an amine group on hexanediamine and a carboxyl group on adipic acid.
How is nylon produced?
PET is formed from a condensation reaction. It is formed from an alcohol and an organic acid. Water forms from between the alcohol and the acid. The two monomers bond, forming the polyester, PET.
Describe the formation of polyethylene terephthalate (PET).
A diamond contains an enormous number of carbon atoms that form a very strong tetrahedral network. Graphite is very soft and has carbon atoms that are bonded in a hexagonal, planer pattern. Weak bonds hold the planes together, causing the graphite to "peel" apart.
Describe the difference between diamonds and graphite.
A saturated fat is one in which all of the carbon atoms form four single covalent bonds. An unsaturated fat is one in which not all of the carbon atoms form four single covalent bonds. Margarine and vegetable shortening are saturated fats, while vegetable oil is an example of an unsaturated fat.
What is the difference between a saturated fat and an unsaturated fat?
Your hair is a natural organic compound made from proteins. Paper is made from cellulose, an organic acid. Citrus fruits contain the organic acid, citric acid. Plastics such as PET, nylon, rubber, and some pharmaceutical drugs are synthetic organic compounds.
What are some examples of natural organic compounds? Of synthetic organic compounds?
When a carbon atom forms four covalent bonds, the bonds are directed toward the corners of a
Name the polymer(s) in the process used to make vulcanized rubber by heating rubber and sulfur.
All organic compounds containing the same functional group are classfied together and behave ______.
