1, alkane

Alkanes are saturated hydrocarbons, which are chain hydrocarbons with only a single carbon-carbon bond, and are the simplest type of organic compounds. Alkane is a general term for many elements saturated hydride.

2, hydrocarbons

Hydrocarbons are a kind of organic compounds. This compound consists of only two elements, carbon and hydrogen, which contains alkanes, alkenes, alkynes, cyclic hydrocarbons and aromatic hydrocarbons, is the base of many other organic compounds? .

3, alkanes

Alkanes are open-chain saturated chain hydrocarbons, carbon atoms in the molecule are connected to a single bond, the rest of the valence of the bond are combined with hydrogen compounds. The general formula is CnH2n+2, and is one of the simplest organic compounds.

Their differences are as follows:

1, whether saturated or not is different:

Alkanes are a kind of alkanes, alkanes are saturated hydrocarbons, while hydrocarbons are not necessarily saturated.

2, the scope is different

Hydrocarbons contain alkanes, alkenes, alkynes, cyclic hydrocarbons and aromatic hydrocarbons, is the base of many other organic compounds, alkanes include alkanes.

Extended information:

Hydrocarbons:

Hydrocarbons can be divided into:

1, open-chain hydrocarbons (hydrocarbon molecules in the carbon atoms in the combination of an open chain) {saturated hydrocarbons (alkanes), unsaturated hydrocarbons olefins and polyolefins (containing carbon-carbon double bond. unstable), alkynes and polyalkynes (containing carbon-carbon triple bond, more unstable)}

2, alicyclic hydrocarbons cycloalkanes (cyclopropanes), cyclic olefins, cycloalkynes

3, aromatic hydrocarbons monocyclic aromatic hydrocarbons (benzene and its homologues), thick-ringed aromatic hydrocarbons (thick-ringed aromatic hydrocarbons such as naphthalene, anthracene, etc. and their homologues), polycyclic aromatic hydrocarbons (polycyclic aromatic hydrocarbons and their homologues)
