The goal of these lessons is to introduce high-school students to the use of oil as an energy source in today’s high-tech world. In the Chemistry of Petroleum 1: What Are Hydrocarbons? students will explore hydrocarbons, the molecular basis of petroleum, and learn to distinguish between organic and inorganic compounds.

Hydrocarbons: Definition. A hydrocarbon is an organic compound made of nothing more than carbons and hydrogens. It is possible for double or triple bonds to form between carbon atoms and even for structures, such as rings, to form. Saturated hydrocarbons have as many hydrogen atoms as possible attached to every carbon. For carbons on the end of a molecular chain, three can be attached. For carbons in the middle of a chain or a ring, two can be attached.

Aromatic hydrocarbons, or arenes, are those that have at least one benzene ring in them. A benzene ring is a ring of six carbon atoms with three double bonds. The formula for benzene, the simplest arene and base structure for all others, is C6H6.

A hydrocarbon is an organic compound made of nothing more than carbons and hydrogens. Hydrocarbons are soluble in oils but not water and are found in petroleum and other natural places. They lend themselves well to making other molecules. For example, alcohols are made by adding an -OH group to a hydrocarbon.

Will carbon as an atom interact with other atoms to form ionic or covalent bonds? It will interact to form covalent bonds. In order to fill its outer shell, how many bonds will carbon make? It will make four bonds. What are hydrocarbons? They are compounds of carbon and hydrogen only. Are hydrocarbons organic or inorganic molecules? Why? Hydrocarbons are organic molecules because they are composed of carbon atoms. Why can carbon form so many different types of compounds? The carbon atom is one of the few that will combine with itself. That means it can form long chains and rings onto which other atoms can be attached. This teacher sheet is a part of the Chemistry of Petroleum 1: What Are Hydrocarbons? lesson.

Remind students that carbon can form double bonds. 1  Using one of the student’s ethane models, add a second toothpick between the marshmallow carbons. Ask students to work in pairs again to re-organize their models so that the carbons and hydrogens have the correct number of shared electrons.

In the Chemistry of Petroleum 3: Distillation of Hydrocarbons, students will be introduced to the distillation and treatment processes by which petroleum is refined to produce useful fuel oils.

Circle or point to the methane chemical formula (CH4). 1  Tell students that this particular organic compound only has two types of atoms—carbon and hydrogen. There are some organic compounds that only contain atoms of carbon and atoms of hydrogen. These compounds are categorized as hydrocarbons.

Using their marshmallows, raisins, and toothpicks, ask students to construct these hydrocarbons: 1  Ethane. 2  Butyne (students should have two types) 3  Hexane. 4  Heptene (students should have three types)

how are hydrocarbons formed
Hydrocarbons are formed by double or triple bonds between carbon atoms or structures. A hydrocarbon is an organic compound made of nothing more than carbons and hydrogens.
