Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds.

The four types most important to human structure and function are carbohydrates, lipids, proteins, and nucleotides. Before exploring these compounds, you need to first understand the chemistry of carbon.

Organic compounds are molecules that contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds). Water (H2O) has no carbon; then, it is not an organic compound. Sodium chloride has neither carbon nor hydrogen; then, it is not an organic compound.

Organic molecules contain carbon; inorganic compounds do not. Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen. The atoms of an organic molecule are typically organized around chains of carbon atoms.

monosaccharide

Any natural molecule that consists of carbon and hydrogen atoms is considered organic. Since glucose is made up of carbon, hydrogen and oxygen atoms, glucose is organic.

Octane is an organic chemical, specifically an alkane, with formula C8H18.

The simplest, most fundamental class of organic molecules is the alkanes. These are molecules consisting only of carbon and hydrogen with only C-H and C-C single bonds. Those alkanes that form rings are called cycloalkanes. Methane (CH4) and ethane (CH3CH3) are alkanes.

Propyne (methylacetylene) is an alkyne with the chemical formula C3H4. It was a component of MAPP gas.

Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas (lower hydrocarbons are generally gaseous in nature) is widely used as a fuel and a chemical building block.

Alkenes contain one or more carbon– carbon double bonds. In ethene, C2H4, two carbon atoms are connected by a double bond. Alkynes contain one or more carbon–carbon triple bonds.

Answer. Since C4H10 follows the general formula CnH2n-2 therefore it is an alkane.
