Alkanes have only one bond (single), alkenes have two (double), and alkynes have three (triple)
In nature, there are many hydrocarbons. They are found in trees and plants, for example, in the form of carotenes, which are pigments found in carrots and green leaves, in addition to fossil fuels. A hydrocarbon polymer, a chainlike molecule made up of numerous units connected, makes up about 98 percent of natural crude rubber. Individual hydrocarbons' shapes and chemistry are determined mainly by the chemical bonds that bind the atoms of their constituent molecules together. This hydrocarbon classification system aids in associating structural characteristics with qualities, but it does not necessitate that a substance is assigned to a specific class.
