    [2]: 4 [4] It is predominantly used as a precursor to trimethylolethane (CH 3 C(CH 2 OH) 3) through a condensation reaction with formaldehyde. This triol is an important intermediate in the production of alkyd resins. It is used in the synthesis of several common aroma compounds (cyclamen aldehyde, helional, lilial). [2]

    It exists in equilibrium with a tautomer CH 3 −C(=O)−CH=C(−OH)−CH 3. The mixture is a colorless liquid. The mixture is a colorless liquid. These tautomers interconvert so rapidly under most conditions that they are treated as a single compound in most applications. [ 2 ]

    This is a free rotation only in the simplest cases like gaseous methyl chloride CH 3 Cl. In most molecules, the remainder R breaks the C ∞ symmetry of the R−C axis and creates a potential V(φ) that restricts the free motion of the three protons. For the model case of ethane CH 3 CH 3, this is discussed under the name ethane barrier. In ...

    3 CN to form the ion (CH 3) 2 CN +. [5] Upon capture of a low-energy electron (less than 1 eV), it will spontaneously dissociate. [6] It is seldom encountered as an intermediate in the condensed phase. It is proposed as a reactive intermediate that forms upon protonation or hydride abstraction of methane with FSO 3 H-SbF 5. The methenium ion is ...

  9. Acetaldehyde - Wikipedia

    en.wikipedia.org/wiki/Acetaldehyde

    The product, CH 3 CH(OCH 2 CH 3) 2, is formally named 1,1-diethoxyethane but is commonly referred to as "acetal". [39] This can cause confusion as "acetal" is more commonly used to describe compounds with the functional groups RCH(OR') 2 or RR'C(OR'') 2 rather than referring to this specific compound — in fact, 1,1-diethoxyethane is also ...
