Structure and Types of Aliphatic Hydrocarbons
Aliphatic hydrocarbons are classified into three main types: alkanes, alkenes, and alkynes, depending on the type of bonds between carbon atoms. Alkanes are saturated hydrocarbons containing only single bonds and follow the general formula
????????????2????+2C
????
H 2????+2
. They are relatively non-reactive and include methane, ethane, and propane. Alkenes, also known as olefins, are unsaturated hydrocarbons with at least one double bond between carbon atoms, giving them the general formula
????????????2????C
????
H 2????
. These compounds, including ethene and propene, are highly reactive and commonly used in polymer manufacture. The third category of alkynes have at least one triple bond between carbon atoms, and the formula is given as
????????????2????−2C
????
????2????−2
. A common alkyne known as acetylene is commonly used for welding purposes, and its name is ethyne.
Reactions and Applications
Aliphatic hydrocarbons show a pattern in their chemical behavior based on their bond structure. Since alkanes are saturated, they usually undergo combustion and substitution reactions and are highly significant as the primary source of energy. The addition reactions like hydrogenation, halogenation, and hydration exhibited by alkenes are more extensively applied in industries for manufacturing alcohols, plastics, and a variety of organic products. Alkynes are even more reactive and engage in addition and polymerization reactions that lead to higher-level materials. It is the very importance of alkenes and alkynes in synthesizing synthetic polymers such as polyethylene and polyacetylene that places them in significant importance in the industry.
