Hydrocarbons, compounds which contain only carbon and hydrogen, can be classified into several types, depending on their structure. When n=2, C₂H₄ (ethene) is formed, when n=3, C₃H₆ (propene) is formed. Therefore, crude petroleum oil contains a list of isoparaffinic alkanes, cycloalkenes or naphthenes, and aromatic or polynuclear aromatic hydrocarbons. X. For the most part, hydrocarbons come from oil . In the presence of oxygen, hydrocarbons produce steam, carbon dioxide and heat during combustion. But methane, ethane, propane, and cycloalkanes are examples of common saturated hydrocarbon because these compounds form by carbon and hydrogen bonding. Hence natural gas consists chiefly of the first six alkanes or hydrocarbons and the percentage of occurrence decreases with increasing molecular weight. Therefore, the general formula for alkynes is CnH(2n-2). (i) Saturated hydrocarbons: These are the types of hydrocarbons in which all carbon-carbon and carbon-hydrogen are … Fuels called fossils come from oil. These are more reactive than alkanes. What are hydrocarbons? They have the general formula of C n H 2n-2 (+yne suffix). Aromatic hydrocarbons (arenes), alkanes, cycloalkanes and alkyne -based compounds are different types of hydrocarbons. Therefore, the main component of natural gas varies according to the source. Therefore, several examples of saturated or unsaturated hydrocarbons coming from natural sources names as the aliphatic hydrocarbon. 2. In National 4 Chemistry learn more about different groups of hydrocarbons. According to the structural dimensions and definition in chemistry, hydrocarbon meaning open chain, cyclic or closed chain, saturated, and unsaturated carbon-hydrogen organic compounds present in our environment. With the development of learning chemistry, the organic hydrocarbon is divided mainly into two types which are pronounced as aliphatic and aromatic. Roofing compounds bitumen or pavement composition and wood preservatives are varied forms of hydrocarbons. The classification was done based on their source and properties. Nonane C9H20 10. Sorry!, This page is not available for now to bookmark. One common example of these polycyclic hydrocarbons is naphthalene. In turn, divided into linear or branched. These are found in coal, tar, oil and some of the cooked foods such as smoked fish, burnt toast, etc. Number of carbon atoms derive the names of the organic compound where one carbon atom presence refers to meth, two is eth, 3 is prop, 4 is but, 5 is pent, 6 is hex, 7 is hept, 8 is oct, 9 is non and 10 carbon atoms presence means dec. Pro Lite, Vedantu … Older chemists classified hydrocarbons as either aliphatic or aromatic. The cyclic benzenoid compound has aromatic properties but the properties of these compounds totally different from alicyclic hydrocarbons molecule. Alkenes and alkynes undergo alkyne metathesis, polymerization and alkene metathesis. Open chain or Aliphatic hydrocarbons. The terms natural gas meaning the total quantity of gaseous hydrocarbons present in used liquid petroleum. Types of Saturated Hydrocarbons. If the alicyclic hydrocarbon is unsaturated, then this hydrocarbon is termed as cycloalkenes. Let's start with alkanes and cycloalkanes. Gaseous hydrocarbons are methane and propane, liquid hydrocarbons are hexane and benzene, low melting solids or waxes hydrocarbons are paraffin wax and naphthalene and polymeric chains of hydrocarbons include polystyrene, polypropylene and polyethylene. Alkanes. to continue to ilmkidunya.com. Enter your email . For example- C 2 H 24, C 3 H 6. The alkenes, sometimes called olefins, are hydrocarbons that contain one or more double bonds per molecule. Octane C8H18 9.
