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 . In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bounded to the rest of the molecule by a single covalent bond (), it can be found on its own in any of three forms: methanide anion (), methylium cation () or methyl radical (). The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed. Methyl cation, anion, and radical Methyl cation The methylium cation () exists in the gas phase, but is otherwise not encountered. Some compounds are considered to be sources of the cation, and this simplification is used pervasively in organic chemistry. For example, protonation of methanol gives an elect ...

Channel 3 (band)
Channel 3, also known as CH3, is an American punk rock band from Cerritos, California. History Channel 3 was formed in 1980 by Mike Magrann (vocals, guitar), Kimm Gardner (guitar), Larry Kelly (bass), and Mike Burton (drums), in the suburban community of Cerritos, California. Their first release was a self-titled EP on California label Posh Boy Records in 1981. "Manzanar", a track from that EP, was played heavily by UK disc jockey John Peel. In 1982, Jack DeBaun become their new drummer and their release ''Fear of Life'' was retitled ''I’ve Got A Gun'' in the UK with some differences in the track-listing. Their next release, ''After The Lights Go Out'', failed to recapture the interest that accompanied their first UK single. Jay Lansford, a former member of The Simpletones, Stepmothers, and The Wigglers who produced CH3's two Posh Boy albums, joined the band in 1984. Their 1985 album for Enigma Records (with Dusty Watson on drums), ''Last Time I Drank...'' revealed that the ...

Methenium
In organic chemistry, methenium (also called methylium, carbenium, methyl cation, or protonated methylene) is a cation with the formula . It can be viewed as a methylene radical (:) with an added proton (), or as a methyl radical (•) with one electron removed. It is a carbocation and an enium ion, making it the simplest of the carbenium ions. Structure Experiments and calculations generally agree that the methenium ion is planar, with threefold symmetry. The carbon atom is a prototypical (and exact) example of sp2 hybridization. Preparation and reactions For mass spectrometry studies at low pressure, methenium can be obtained by ultraviolet photoionization of methyl radical, or by collisions of monatomic cations such as and with neutral methane. In such conditions, it will react with acetonitrile to form the ion . Upon capture of a low-energy electron (less than ), it will spontaneously dissociate. It is seldom encountered as an intermediate in the condensed phase. It is ...

Methyl Radical
Methyl (also systematically named trihydridocarbon) is an organic compound with the chemical formula (also written as •). It is a metastable colourless gas, which is mainly produced ''in situ'' as a precursor to other hydrocarbons in the petroleum cracking industry. It can act as either a strong oxidant or a strong reductant, and is quite corrosive to metals. Chemical properties Its first ionization potential (yielding the methenium ion, ) is . Redox behaviour The carbon centre in methyl can bond with electron-donating molecules by reacting: : + R• → Because of the capture of the nucleophile (R•), methyl has oxidising character. Methyl is a strong oxidant with organic chemicals. However, it is equally a strong reductant with chemicals such as water. It does not form aqueous solutions, as it reduces water to produce methanol and elemental hydrogen: :2  + 2  → 2  + Structure The molecular geometry of the methyl radical is trigonal planar (bond ...

Channel 3 (Thailand)
Channel 3 or Channel 3 HD ( th, สถานีโทรทัศน์ไทยทีวีสีช่อง 3 (ช่อง 3 เอชดี ช่อง 33)) is a Thai free-to-air television network that was launched on 26 March 1970 as Thailand's first commercial television station. Channel 3 is operated by BEC Multimedia Company Limited (“BECM”), a subsidiary of publicly traded company BEC World Public Company Limited. The network is headquartered in the Maleenont Towers of Bangkok. History Channel 3 was launched on 26 March 1970 at 10:00 Bangkok Time by Prime Minister Field Marshal Thanom Kittikachorn. This broadcast area was only limited to the Bangkok Metropolitan Area during its early years. On 1 January 1985, it launched its first teletext service known as Infonet. On 1 January 1987, started to air in stereo and, during the 1990s, its stereo broadcast was introduced into its VHF free-to-air station nationwide. TV3 was also experimenting with bilingual transmiss ...
