    en.wikipedia.org/wiki/Methane

    Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.

    en.wikipedia.org/wiki/Methyl_group

    In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...

    For example, (CH 3) 2 CHCH 2 CH 3 (isopentane) is named 2-methylbutane, not 3-methylbutane. If there are multiple side-branches of the same size alkyl group, their positions are separated by commas and the group prefixed with multiplier prefixes depending on the number of branches. For example, C(CH 3) 4 (neopentane) is named 2,2 ...

    This would still exclude urea. Moreover, this definition still leads to somewhat arbitrary divisions in sets of carbon-halogen compounds. For example, CF 4 and CCl 4 would be considered by this rule to be "inorganic", whereas CHF 3, CHCl 3, and C 2 Cl 6 would be organic, though these compounds share many physical and chemical properties ...

    4) is a liquid. Many fluoroalkanes, however, go against this trend and have lower melting and boiling points than their nonfluorinated analogues due to the decreased polarizability of fluorine. For example, methane (CH 4) has a melting point of −182.5 °C whereas tetrafluoromethane (CF 4) has a melting point of −183.6 °C. [citation needed]

    This may be solved to find the steady-state concentration of •CH 3 radicals as [•CH 3] = (k 1 / 2k 4) 1/2 [CH 3 CHO] 1/2. It follows that the rate of formation of CH 4 is d[CH 4]/dt = k 2 [•CH 3][CH 3 CHO] = k 2 (k 1 / 2k 4) 1/2 [CH 3 CHO] 3/2. Thus the mechanism explains the observed rate expression, for the principal products CH 4 and CO.

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
