2] 2• (X̃ 3 B 1) + H 2 O → [CH 3] • + [HO] • [CH 2] (ã 1 A 1) + H 2 O → H 2 CO + H 2 or H 3 COH. The singlet state is also more stereospecific than the triplet. [10] Methylene spontaneously autopolymerises to form various excited oligomers, the simplest of which, is the excited form of the alkene ethylene. The excited oligomers ...
At about 270 Pa of pressure and ambient temperature, the methane ion CH + 4 will react with neutral methane to yield methanium and a methyl radical: [11] CH + 4 + CH 4 → CH + 5 + CH 3 • The methanium ion can also be made in the gas phase via the reaction of methane and an H + ion (i.e. a proton). [citation needed] CH 4 + H + (g) → CH + 5

The [W 12 O 40] 8-cage. Metatungstates feature the doubly protonated derivative of this cage, i.e. [H 2 W 12 O 40] 6-. [1] Sodium metatungstate is the inorganic compound with the formula Na 6 [H 2 W 12 O 40], sometimes written 3Na 2 WO 4 ·9WO 3 ·H 2 O. It is also referred to as sodium polytungstate (SPT).
2,4-Dichloroaniline is an organic compound with the formula C 6 H 3 Cl 2 NH 2. It is one of six isomers of dichloroaniline , a chlorinated variant of aniline . It appears as beige crystals.
2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C 6 H 3 Cl 3 O.It has been used as a fungicide and herbicide. [2] Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly ...
R-dichlorprop (dichlorprop-p). Dichlorprop possesses a single asymmetric carbon and is therefore a chiral molecule, however only the R-isomer is active as an herbicide.When dichlorprop was first marketed in the 1960s, it was sold as racemic mixture of stereoisomers, but since then advances in asymmetric synthesis have made possible the production of the enantiopure compound.
