The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [1] [2]
Three Rules for Naming Alkanes. Choose the longest, most substituted carbon chain containing a functional group. A carbon bonded to a functional group must have the lowest possible carbon number. If there are no functional groups, then any substituent present must have the lowest possible number.
30 Σεπ 2024 · Find the longest continuous carbon chain in the molecule, and use that as the parent name. This molecule has a chain of eight carbons—octane—with two methyl substituents. (You have to turn corners to see it.)
23 Ιαν 2023 · Alkanes with unbranched carbon chains are simply named by the number of carbons in the chain. The first four members of the series (in terms of number of carbon atoms) are named as follows: CH 4 = methane = one hydrogen-saturated carbon. C 2 H 6 = ethane = two hydrogen-saturated carbons. C 3 H 8 = propane = three hydrogen-saturated carbons.

The following is a list of straight-chain alkanes and their common names, sorted by number of carbon atoms.
Triple bonds are named in a similar way using the suffix -yne. The position of the multiple bond (s) within the parent chain is (are) indicated by placing the number (s) of the first carbon of the multiple bond (s) directly in front of the base name. Here is an important list of rules to follow:
