Methane (US: /ˈm?θe?n/ or UK: /ˈmiːθe?n/) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas.
Similarly, it is asked, what is ch4 stand for it?
CH4 stands for Methane, Natural Gas (chemistry; carbon atom surrounded by 4 hydrogen atoms) Suggest new definition. This definition appears frequently and is found in the following Acronym Finder categories: Science, medicine, engineering, etc.

What is the chemical name for ch4?
In CH4 the sharing is equal. Therefore CH4 is a nonpolar molecule. While there may be a difference in electronegativity between the Carbon and Hydrogen bonds, there is no net (overall) polarity. That makes CH4 a nonpolar molecule.
methane (CH4) Colorless, odorless, but flammable hydrocarbon gas that is the chief constituent (about 75 to 99 percent) of natural gas. It is non-toxic but works like an asphyxiant and is one of the major hothouse gases. Methane is converted into methanol by catalytic oxidation.

Methane is the primary component of natural gas – a common fuel source. If methane is allowed to leak into the air before being used—from a leaky pipe, for instance—it absorbs the sun's heat, warming the atmosphere. For this reason, it's considered a greenhouse gas, like carbon dioxide.
2) Organic compounds almost always contain one or more C-H bonds. 3) Organic compounds are almost always molecules (as opposed to salts). Thus, all bonds are typically covalent in organic compounds. Methane (CH4) is the prototypical organic molecule.
Yes ch4 is a covalent compound . Carbon has 4 valency and 4 hydrogen share electrons with 1 carbon and form 4 covalent bonds .Hope this helps . yes, CH4 is a covalent compound for being ionic the electronegativity of hydrogen is 2.2 and carbon is 2.55. so ch4 which has four c-h bond can be termed as a covalent compund.
According to a Danish study, the average cow produces enough methane per year to do the same greenhouse damage as four tons of carbon dioxide. So is this significantly contributing to global warming? Let's start with how and why cows produce so much methane gas.
Uses: Methane - meth - CH4 is a colorless, flammable, nontoxic gas with a sweet, oil type odor. Methane is useful in the testing of gas appliances which are to be used for natural gas areas.
Methane is an odorless, colorless, flammable gas. It is used primarily as fuel to make heat and light. It is also used to manufacture organic chemicals. Methane can be formed by the decay of natural materials and is common in landfills, marshes, septic systems and sewers.
Methane emissions get produced wherever there are fossil fuels. It gets released whenever fossil fuels get extracted from the earth. Whether it is natural gas (which is in most part methane), coal or petroleum. Finally some methane is also produced during fossil fuel combustion.
All compounds are molecules but not all molecules are compounds. Molecular hydrogen (H2), molecular oxygen (O2) and molecular nitrogen (N2) are not compounds because each is composed of a single element. Water (H2O), carbon dioxide (CO2) and methane (CH4) are compounds because each is made from more than one element.
. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Its chief use is as feedstock for ethylene production.
Methane gas is relatively non-toxic; it does not have an OSHA PEL Standard. Its health affects are associated with being a simple asphyxiant displacing oxygen in the lungs. Methane is extremely flammable and can explode at concentrations between 5% (lower explosive limit) and 15% (upper explosive limit).
Human-related Sources. In the United States, the largest methane emissions come from the decomposition of wastes in landfills, ruminant digestion and manure management associated with domestic livestock, natural gas and oil systems, and coal mining.
Chemical and Physical Properties of Methane. The carbon atom central to the methane molecule has 4 valence electrons and thus needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms have a 109 degree bond angle giving the molecule a tetrahedral geometry .
Methane is not generally considered a toxic gas, however it is extremely flammable even in low concentrations when mixed with other chemicals – it is also an asphyxiant as it will displace oxygen. This is particularly dangerous in confined spaces working.
Hydrogen is the first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight [1.00784; 1.00811]. Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2.
A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH3. In formulas, the group is often abbreviated Me. Such hydrocarbon groups occur in many organic compounds. It is a very stable group in most molecules.
Gas is far and away the cleanest-burning fossil fuel, generating at least 50 percent less carbon per kilowatt hour than coal, and almost zero sulfur oxides, mercury and particulate ash.
One molecule of methane, (the [g] referred to above means it is gaseous form), combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy. Natural gas is the cleanest burning fossil fuel.
