Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Because carbon has 4 electr…

Uses of Hydrocarbons
- Hydrocarbons are widely used as fuels. For example LPG (liquefied petroleum gas), CNG (Liquefied natural gas).

Hexane is an unbranched alkane containing six carbon atoms. It has a role as a non-polar solvent and a neurotoxin.
Which is an hydrocarbon?
Hydrocarbons are compounds comprised exclusively of carbon and hydrogen and they are by far the dominant components of crude oil, processed petroleum hydrocarbons (gasoline, diesel, kerosene, fuel oil, and lubricating oil), coal tar, creosote, dyestuff, and pyrolysis waste products.
What is a hydrocarbon simple definition?
The term hydrocarbon refers to an organic chemical compound that is composed exclusively of hydrogen and carbon atoms. Hydrocarbons are naturally-occurring and form the basis of crude oil, natural gas, coal, and other important energy sources.
What are hydrocarbons made of quizlet?
What is a hydrocarbon? It is a molecule composed of carbon and hydrogen only.
What are hydrocarbons and what is their importance quizlet?
Hydrocarbons are organic molecules made up of carbon and hydrogen atoms. Hydrocarbons are primarily found in crude oil, and serve as the fuel source for much of our civilization.
What is hydrocarbon with example?
(a) Hydrocarbon is a compound of hydrogen and carbon. Examples for hydrocarbons are methane (CH4) , ethane (C2H6)and ethyne (C2H2). All these compounds are hydrocarbons as they are only made of hydrogen and carbon elements which is evident from their respective molecular formulae.
What is hydrocarbon used for?
The most important use of hydrocarbons is for fuel. Gasoline, natural gas, fuel oil, diesel fuel, jet fuel, coal, kerosene, and propane are just some of the commonly used hydrocarbon fuels. Hydrocarbons are also used to make things, including plastics and synthetic fabrics such as polyester.
What type of atoms are found in hydrocarbons?
A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations.
What types of atoms is are found in hydrocarbons quizlet?
What is a hydrocarbon? A) It is a molecule composed of carbon and hydrogen only.
Why do hydrocarbons make good fuels quizlet?
Hydrocarbons with small molecules make better fuels than hydrocarbons with large molecules because they are volatile, flow easily and are easily ignited.
What is the definition of hydrocarbon Brainly?
Hydrocarbon, any of a class of organic chemical compounds composed only of the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations.
Which formula is a hydrocarbon?
The general formula for a saturated hydrocarbon containing one ring is CnH2n. For most compounds, information beyond the chemical formula will be needed to elucidate their structure. However, the ratio of C:H in a chemical formula can provide insights into the chemical structure.
Are hydrocarbons polar or nonpolar Why?
Most hydrocarbons are nonpolar because of the close electronegativities of C and H atoms. As such, they dissolve only sparingly in H 2O and other polar solvents. Small hydrocarbons, such as methane and ethane, are gases at room temperature, while larger hydrocarbons, such as hexane and octane, are liquids.
What are 3 examples of hydrocarbons?

What is a hydrocarbon GCSE?
A hydrocarbon is a molecule that is made out of only hydrogen atoms and carbon atoms. The carbon atoms form a chain and the hydrogen atoms are bonded to the carbon chain. These are all examples of hydrocarbons. These are all saturated hydrocarbons. This means that there are no double bonds.
What are hydrocarbons for Class 8?
Hydrocarbons are organic compounds that are entirely made up of only two kinds of atoms – carbon and hydrogen. Typically, hydrocarbons are colourless gases that have very weak odours.
Why are hydrocarbons called hydrocarbons?
The term hydrocarbon refers to the most basic type of organic molecules. As suggested by their name, they are comprised of only 2 elements: hydrogen and carbon. Hydrocarbon molecules have one or more central carbon atoms in a branched or chain-like structure, surrounded by hydrogen atoms.

What is the classification of hydrocarbons?
Nineteenth-century chemists classified hydrocarbons as either aliphatic or aromatic on the basis of their sources and properties .
How does the use of hydrocarbons affect global warming and climate change?
The ever-increasing use of fossil fuels in industry, transportation, and construction has added large amounts of CO 2 to Earth’s atmosphere. Atmospheric CO 2 concentrations fluctuated between 275 and 290 parts per million by volume (ppmv) of dry air between 1000 CE and the late 18th century but had increased to 316 ppmv by 1959 and rose to 412 ppmv in 2018. CO 2 behaves as a greenhouse gas —that is, it absorbs infrared radiation (net heat energy) emitted from Earth’s surface and reradiates it back to the surface. Thus, the substantial CO 2 increase in the atmosphere is a major contributing factor to human-induced global warming.
What are hydrocarbons classified as?
Nineteenth-century chemists classified hydrocarbons as either aliphatic or aromatic on the basis of their sources and properties. Aliphatic (from Greek aleiphar, “fat”) hydrocarbons derive from the chemical breakdown of fats or oils. They are divided into alkanes, alkenes, and alkynes.
How are organic compounds named?
The naming of organic compounds is facilitated through the use of formal systems of nomenclature. Nomenclature in organic chemistry is of two types: common and systematic. Common names originate in many different ways but share the feature that there is no necessary connection between name and structure. The name that corresponds to a specific structure must simply be memorized, much like learning the name of a person. Systematic names, on the other hand, are keyed directly to molecular structure according to a generally agreed upon set of rules. The most widely used standards for organic nomenclature evolved from suggestions made by a group of chemists assembled for that purpose in Geneva in 1892 and have been revised on a regular basis by the International Union of Pure and Applied Chemistry (IUPAC). The IUPAC rules govern all classes of organic compounds but are ultimately based on alkane names. Compounds in other families are viewed as derived from alkanes by appending functional groups to, or otherwise modifying, the carbon skeleton.
How many carbons are in an alkane?
Alkanes with branched chains are named on the basis of the name of the longest chain of carbon atoms in the molecule, called the parent. The alkane shown has seven carbons in its longest chain and is therefore named as a derivative of heptane, the unbranched alkane that contains seven carbon atoms.
What are the elements that make up a hydrocarbon?
hydrocarbon, any of a class of organic chemical compounds composed only of the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations. Hydrocarbons are the principal constituents of petroleum and natural gas. They serve as fuels and lubricants as well as raw materials for the production of plastics, fibres, rubbers, solvents, explosives, and industrial chemicals.
