Math in focus grade 2b
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.: 620 Hydrocarbons are examples of group 14 hydrides. Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Hydrocarbons are generally colourless and hydrophobic with only weak odours.

The simplest organic molecules, hydrocarbons, contain only hydrogen atoms bonded to a carbon backbone. The carbon backbone ranges from one carbon atom in methane, or natural gas, to thousands of carbon atoms, such as in polyethylene, a commonly used plastic. Forming the structural basis of many biomolecules in living cells, hydrocarbons are utilized as starting materials and released as breakdown products during many chemical reactions.

The RNA molecule is an intermediate between the DNA molecule and the protein. This lets the DNA stay pristine and protected, away from the caustic chemistry of the cytoplasm outside the nucleus. Also, many copies of an RNA molecule can be made which enables the amplification of genetic information.

Carbon atoms always have four bonds: four single bonds, two single and one double bond, two double bonds, or a single bond and a triple bond. Although carbon is the basic building block, organic compounds usually have hydrogen atoms as well. Oxygen and nitrogen are also common, but almost any other element can be found in organic compounds.
