Saturated Hydrocarbon and It s applications

In this lecture you will see how saturated hydrocarbon like Alkanes can be used in our life applications

Petroleum, along with natural gas, provides nearly 90% of the organic materials for the synthesis and manufacture of synthetic fibers,
plastics, drugs, dyes, adhesives, paints, and a multitude of other products.

first : How Do We Write Structural Formulas of Alkanes?
Alkanes are members of a larger class of organic compounds called hydrocarbons ( figure 2.1). as example of these hydrocarbon is Butane, CH3CH2CH2CH3, is the fuel in this lighter. Butane molecules are present in both the liquid and gaseous states in the lighter.
Also we can see
second :What Are Constitutional Isomers?
Constitutional isomers are compounds that have the same molecular formula but different structural formulas. By “different structural formulas” we mean that they differ in the kinds of bonds (single, double, or triple) and/ or in the connectivity of their atoms. For the molecular formulas CH4, C2H6, and C3H8, only one connectivity of their atoms is possible, so there are no constitutional isomers for these molecular formulas. For the molecular formula C4H10, however, two structural formulas are possible: In butane, the four carbons are bonded in a chain; in 2-methylpropane, three carbons are bonded in a chain with the fourth carbon is a branch on the chain.
