Unsaturated hydrocarbons are widely used as high number of hydrogen atoms. Image Courtesy: 1. In its highly refined form, liquid methane can also serve as rocket fuel. Examples: Methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10) are all saturated hydrocarbons because they contain only carbon-carbon single bonds. (moisture). CTRL + SPACE for auto-complete. ‘’Unsaturated’’ means more hydrogen atoms may be added to the hydrocarbon to The number of possible chain isomers for an alkane depends on the total number of carbon atoms in it. (Hons) degree in Applied Science and a Master of Science degree in Industrial Chemistry. Alkenes - These unsaturated hydrocarbons are molecules that … Unsaturated Hydrocarbons: Unsaturated hydrocarbons are more reactive. Saturated hydrocarbons are mainly used for heating and cooking Saturated Hydrocarbons: Saturated hydrocarbons are hydrocarbons with only single covalent bonds. Examples include alkanes and cycloalkanes. 1. Ethane, C 2 H 6, is an example of a saturated hydrocarbon. Hence, unsaturated hydrocarbons are more reactive than saturated hydrocarbons. Saturated and unsaturated hydrocarbons show different characteristics because of these structural differences. Acetylene, propyne, butyne are some examples for alkynes. Alkenes, alkynes and aromatic hydrocarbons are examples of : Cengage Learning, 2012. Methane, the simplest alkane, is used as a fuel in several automobiles, water heaters, and ovens. Saturated hydrocarbons contain only single covalent bonds whereas unsaturated hydrocarbons contain at least one or more double or triple carbon-carbon bond. and many other necessities. What are Unsaturated Hydrocarbons – Definition, Structure, Types, Properties 3. Stoker, H. Stephen. Examples of alkenes include ethene, propene, butene, etc. 2. Saturated hydrocarbons are hydrocarbons that contain only Examples of saturated hydrocarbons include alkanes and cycloalkane families of hydrocarbons. The longer the chain, the higher the melting or boiling point. pesticides, fuel, paints and many other necessities. Examples of unsaturated hydrocarbons include: © 2020 Reproduction of content from this website, either in whole or in part without permission is prohibited. Alkanes are examples of saturated hydrocarbons. Because of the flammability of saturated hydrocarbons that ultimately release a lot of energy, saturated hydrocarbons are often used as a fuel source of vehicle and airplane engines. The main difference between saturated and unsaturated hydrocarbon is that saturated hydrocarbons contain only single covalent bonds between carbon atoms, whereas unsaturated hydrocarbons contain at least one double or triple covalent bond in the main chain. 6th ed. Unsaturated Hydrocarbons: These are mainly obtained from plants (plant pigments, waxes, proteins, vegetable oils etc.). compared to saturated hydrocarbons. flame. Unsaturated hydrocarbons are more reactive when The simplest form of saturated hydrocarbons includes methane (CH4), ethane (C2H6), propane (C3H8) etc. Saturated hydrocarbons have more hydrogen Saturated hydrocarbons burn and give a blue, non-sooty flame in air. The propellant used in several aerosol sprays is a saturated hydrocarbon known as propane. Saturated hydrocarbons include the alkanes, whereas unsaturated hydrocarbons include alkene, alkynes and aromatic hydrocarbons. Unsaturated hydrocarbons feature at least one double or triple bond between two adjacent carbon atoms. The simplest form of unsaturated hydrocarbon is ethylene, which is important as a plant hormone that triggers the ripening of fruits. A hydrocarbon is an organic compound whose only constituents are carbon and hydrogen. hydrocarbons. Home » Science » Chemistry » Organic Chemistry » Difference Between Saturated and Unsaturated Hydrocarbons. (moisture). as branched chains and aromatic compounds. or triple covalent bonds between adjacent carbon atoms. : S. Chand, 2016. There are three types of unsaturated hydrocarbons, namely; (a) alkenes, which contain one or more double bond (C=C), (b) alkynes, which contains one or more triple bonds (C≡C), and (c) aromatic hydrocarbons, which consist of a delocalized bonding resulting in a six-membered carbon ring. This is why these compounds are called saturated hydrocarbons. General, organic, and biological chemistry. content and therefore during combustion or heating, they produce less water non-polar organic solvents such as benzene. Hence, the reactivity of unsaturated hydrocarbon increases with a number of multiple bonds present in the main chain.
