Which is the most abundant hydrocarbon in the atmosphere?

By contrast, CH4 is by far the most abundant hydrocarbon in the atmosphere, in part because of its 8-year atmospheric lifetime (7), which allows it to be widely distributed throughout both the northern and southern hemi- spheres.

Which is most abundant hydrocarbon pollutant?

What is hydrocarbon in the atmosphere?

Sometimes unburned hydrocarbons are released into the air during incomplete combustion. Burning fossil fuels, including gasoline in automobile engines, releases some hydrocarbons into the air. In a typical urban environment, the atmospheric concentration of hydrocarbons is around 3 ppm (parts per million).

Which of the following is the most common hydrocarbon?

Hydrocarbons are made up of only carbon and hydrogen atoms. The most common is also the smallest, methane.

Which of the following is most abundant hydrocarbon pollutant a butane B ethane C methane D propane?

Detailed Solution. The correct answer is Methane. It is the simplest hydrocarbon consisting of one carbon atom and four hydrogen atoms and the simplest hydrocarbon, is the most abundant hydrocarbon pollutant.

Which is the most abundant of all the hydrocarbon pollutants in the atmosphere?

Which is the most abundant hydrocarbon in the atmosphere Mcq?

Explanation: The most abundant hydrocarbon which is emitted into the atmosphere by biological activity is methane.

Which is the source of pollutant gases with hydrocarbon?

Contaminated lands, oil spillage, pesticides, automobile oils, and urban stormwater discharges are the major causes for the hydrocarbon contamination. Oil spill is one of the major sources of hydrocarbon contamination.

What are the largest hydrocarbons?

Earlier this year, the University of Michigan chemist published a paper with coworker Zhifu Xu announcing the synthesis and characterization of the largest all-hydrocarbon molecule ever made—C ₁₁₃₄ H ₁₁₄₆ [ Angew.

What are the 4 types of hydrocarbons?

Alkanes, Alkenes, Alkynes and Aromatic hydrocarbons are the 4 types of hydrocarbons.

What type of hydrocarbon is methane?

Methane is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms. Methane is a powerful greenhouse gas.

Is oxygen a hydrocarbon?

No, hydrocarbons do not contain oxygen. Hydrocarbons are chemical compounds that only contain carbon and hydrogen atoms.

Is ethane a hydrocarbon?

ethane, a colourless, odourless, gaseous hydrocarbon (compound of hydrogen and carbon), belonging to the paraffin series; its chemical formula is C₂H₆. Ethane is structurally the simplest hydrocarbon that contains a single carbon–carbon bond.

Which is not a primary pollutant?

Solution(By Examveda Team) Ozone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source. Similarly, sulphuric acid is also not a primary pollutant.

Which of the following is an inorganic pollutant?

The correct answer is Hydrogen sulphide. Pollutants like carbon dioxide (CO₂), carbon monoxide (CO), sulfur dioxide (SO₂), nitrous oxide (NO), and nitrogen dioxide (NO₂), Hydrogen sulfide (H₂S) are collectively called Inorganic gaseous pollutants.

Which of the following pollutants are responsible for the cause of smog?

Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents. When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog.

What is the simplest hydrocarbon?

Methane (CH 4​start subscript, 4, end subscript), the simplest hydrocarbon molecule, consists of a central carbon atom bonded to four hydrogen atoms.

What are the two main classes of hydrocarbons?

There are many hydrocarbons. They can be classified into two main classes: aliphatic and the aromatic hydrocarbons. Aliphatic hydrocarbons are composed of catenated carbon chain. In acyclic compounds, the carbon chain are straight or branched.

Which hydrocarbon will be most stable?

Diamond monohydride: the most stable three-dimensional hydrocarbon.

What are the three types of hydrocarbons?

There are three types of aliphatic hydrocarbons. Alkanes are aliphatic hydrocarbons with only single covalent bonds. Alkenes are aliphatic hydrocarbons that contain at least one C–C double bond, and alkynes are aliphatic hydrocarbons that contain a C–C triple bond.

What is a pure hydrocarbon?

With relation to chemical terminology, aromatic hydrocarbons or arenes, alkanes, alkenes and alkyne-based compounds composed entirely of carbon or hydrogen are referred to as "pure" hydrocarbons, whereas other hydrocarbons with bonded compounds or impurities of sulphur or nitrogen, are referred to as "impure", and ...

What are the examples of hydrocarbons?

Overall, examples of hydrocarbons are methane, ethane, propane, and butane.

Which gas is most pollutant in atmosphere?

2.1. 2 Sulphur dioxide. Sulphur dioxide is the pollutant gas most commonly found in the atmosphere and is usually present in high concentrations in urban and industrial locations.

Which gas is the main pollutants for global warming?

Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.

Which gas is the main pollutant responsible for global warming?

Carbon dioxide (CO₂) is the primary greenhouse gas emitted through human activities. In 2020, CO₂ accounted for about 79% of all U.S. greenhouse gas emissions from human activities.
