31 Saturated Hydrocarbon Examples: Facts You Should Know


Carbon containing compounds attached with hydrogen atom with a single bond are saturated hydrocarbons. Following are the various saturated hydrocarbon examples. 

Following is the list of saturated hydrocarbons examples:

  1. Alkanes (CnH2n+2)

2. Cycloalkanes (CnH2n)

Alkanes (CnH2n+2)

There are two types of saturates hydrocarbons i.e.  alkanes and cycloalkanes. Alkanes have general formula of CnH2n+2. Alkanes are generally not reacted with oxidizing and reducing agents, acids and bases and other organic compounds. It can form both straight chain and branch chain alkanes and show various isomers.

Methane (CH4)

Methane contains 1 C and 4 H atoms and it is commonly known as Marsh gas / methyl hydride. It is gas having molecular formula CH4 is the smallest.

Ethane (C2H6)

Ethane is the flammable gas which is non-toxic in nature and having no odour. It has 2 C and 6 H and only forms strait chains and can also write as CH3 – CH3.

Propane (C3H8)

Prpoane is a gas used in liquefied petroleum gas (LPG). It is also form only straight chains written as CH3 – CH2 – CH3.

Butane (C4H10)

Butane (CH3 – (CH2)2 – CH3) is also a gas used in LPG’s which gives clear flame. It can form both straight and branched chains and written as follows.

Pentane (C5H12)

Pentane basically occurs in liquid form at room temperature. It has long chain of 5 C atoms represented as CH3 – (CH2)3 – CH3. It is present in both straight chain and branched chains and shows the following isomers.

Dodecane (C12H26)

Long chain of twelve carbon atom containing hydrocarbon named as Dodecane. It can denoted as CH3 – (CH2)10 – CH3.

Pentadecane (C15H32)

Fifteen carbon atoms containing chain of hydrocarbons are Pentadecane. It can be written as CH3 – (CH2)13 – CH3.

Hexadecane (C16H34)

The saturated hydrocarbon having sixteen carbon atoms in its longest chain is Hexadecane. It is occurs in fuel especially in diesel and present in straight form in it.

Eicosane (C20H42)

Twenty carbon atom containing hydrocarbon is eicosane. The following hydrocarbons after eicosane i.e. with 21 C atom chain is heneicosane, C22 docosane, C23 tricosane and so on.

Triacontane (C30H62)

Carbon chain with thirty carbon atoms is known as Tricontane. The further carbon chain of tricontane has named as methyltricontane (C31H64), dotricontane (C32H66), tritricontane (C33H68) and so on.

Tetracontane (C40H82)

Tetracontane is alkane contains longest chain of 40 carbon atoms. It is further chains of tetracontane followed with names hen (C41), do (C42), tri (C43), tetra (C44), penta (C45) with tetracontane.

Pentacontane (C50H102)

Longest chain of Fifty carbon atoms containing alkanes are pentacontane. It is followed with the same sequence of its family alkane like henpentacontane (C51), dopentacontane (C52), tripentacontane (C53), etc.

Hexacontane (C60H122)

Hundred carbon chain containing hydrocarbons or alkanes are known to be Hectane. It has following hydrocarbon chains like Henhectane (C101), Dohectane (C102), Trihectane (C103), etc.

Cycloalkanes (CnH2n)

The alkanes containing carbon chain which get joined in a cyclic manner to form a ring are known as cycloalkanes. It has two less hydrogen atoms than straight chain alkanes and thus has general formula CnH2n. Due to presence of single bond within carbon atoms no free rotation occurs in cycloalkane structures.

Dodecahedrane consists of 20 carbon atoms with 20 hydrogen atoms in its structure which forms a polyhedron contain 12 faces.

Conclusion:

Saturated hydrocarbons are single bond containing hydrocarbons. There are two types of saturated hydrocarbons, alkanes and cycloalkanes. Alkanes can form straight and branch chain hydrocarbons. Cycloalkanes having 2 less hydrogen atoms than alkanes and form ring structures as the carbon atoms get joined with each other.
