They are elements.
Some examples of organic compounds that do not contain hydrogen include carbon tetrachloride, carbon disulfide, and carbon dioxide.
Molecules that contain only carbon and hydrogen are called hydrocarbons. Some examples are methane, CH4, ethane, C2H6, and propane, C3H8.
Five examples of elements are Boron, Oxygen, Hydrogen, Carbon, and Calcium. To find more, see the link to Wikipedia in the related links (below).
Inorganic matter does not contain carbon and hydrogen. Examples include minerals, metals, and gases like oxygen and nitrogen.
Water is an oxide of hydrogen. Carbon dioxide is an oxide of carbon. Rust is an oxide of iron.

Elements.
Inorganic matter does not contain carbon and hydrogen. Examples include minerals, metals, and gases like oxygen and nitrogen.
Hydrogen, Helium, Carbon, Gold, Silver, Oxygen
Water is an oxide of hydrogen. Carbon dioxide is an oxide of carbon. Rust is an oxide of iron.
Examples of substances that are elements include hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon
oxygen nitrogen neon carbon dioxide hydrogen Argon, neon, hydrogen, oxygen and nitrogen are gasses.
A compound that only contains carbon and hydrogen is called a hydrocarbon. Examples include methane, ethane, propane, and butane.
Carbon dioxide and carbon monoxide are not examples of organic chemistry because they do not contain hydrogen atoms bonded to carbon atoms. Organic chemistry focuses on compounds that contain carbon-hydrogen bonds, whereas carbon dioxide (CO2) and carbon monoxide (CO) consist of carbon atoms bonded to oxygen atoms instead.
