Can You Name the First 10 Alkanes

Alkanes are the simplest hydrocarbon chains. These are organic molecules that consist only of hydrogen and carbon atoms in a tree-shaped structure (acyclic or not a ring). These are commonly known as paraffins and waxes. Here is a list of the first 10 alkanes. methane CH4 ethane C2H6 propane C3H8 butane C4H10 pentane C5H12 hexane C6H14 heptane C7H16 octane C8H18 nonane C9H20 decane C10H22 Table of the First 10 Alkanes How Alkane Names Work Each alkane name is built from a prefix (first part) and a suffix (ending). The -ane suffix identifies the molecule as an alkane, while the prefix identifies carbon skeleton. The carbon skeleton is how many carbons are linked to each other. Each carbon atom participates in 4 chemical bonds. Every hydrogen is joined to a carbon. The first four names come from the names methanol, ether, propionic acid, and butyric acid. Alkanes that have 5 or more carbons are named using prefixes that indicate ​the  number of carbons. So, pent- means 5, hex- means 6, hept- means 7, and so on. Branched Alkanes The simple branched alkanes have prefixes on their names to distinguish them from the linear alkanes. For example, isopentane, neopentane, and n-pentane are names of branched forms of the alkane pentane. The naming rules are somewhat complicated: Find the longest chain of carbon atoms. Name this root chain using the alkane rules.Name each side chain according to its number of carbons, but change the suffix of its name from -ane to -yl.Number the root chain so that the side chains have the lowest possible numbers.Give the number and name of the side chains before naming the root chain.If multiples of the same side chain are present, prefixes such as di- (two) and tri- (for three) indicate how many of the chains are present. The location of each chain is given using a number.The names of multiple side chains (not counting di-, tri-, etc. prefixes) are given in alphabetical order before the name of the root chain. Properties and Uses of Alkanes Alkanes that have more than three carbon atoms form structural isomers. Lower molecular weight alkanes tend to be gases and liquids, while larger alkanes are solid at room temperature. Alkanes tend to make good fuels. They are not very reactive molecules and do not have biological activity. They do not conduct electricity and not appreciably polarized in electric fields. Alkanes dont form hydrogen bonds, so they arent soluble in water or other polar solvents. When added to water, they tend to decrease the entropy of the mixture or increase its level or order. Natural sources of alkanes include natural gas and petroleum. Sources Arora, A. (2006). Hydrocarbons (Alkanes, Alkenes And Alkynes). Discovery Publishing House Pvt. Limited.
