The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2. The two enantiomers are denoted (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane (the other simplest chiral alkane is its structural isomer 3 ...
Monobromopentanes are bromopentanes containing one bromine atom, with the formula C 5 H 11 Br. There are three isomers of unbranched monobromopentane: 1-Bromopentane; 2-Bromopentane [1] (chiral) 3-Bromopentane; There are four isomers of monobromopentane based on 2-methylbutane: 1-Bromo-2-methylbutane (chiral) 1-Bromo-3-methylbutane; 2-Bromo-2 ...
2-MDP synthesis. In a variation of the nitrile-aldol reaction, combination of benzophenone (1) and propionitrile (2), in the presence of sodamide base and ethyl ether solvent, leads to 3-hydroxy-2-methyl-3,3-diphenylpropanenitrile (3). [5] The reduction of the intermediate nitrile group with lithium aluminium hydride completes the synthesis of ...
As of early 1990s, it was present in American [4] and European [5] gasoline in small amounts, and by 2011 its share in US gas varied between 2 and 8%. [6] Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane number (RON) of 75, motor octane number (MON) of 77, and cetane number (CN ...
3,4-Methylenedioxyphenylpropan-2-one [1] or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via ...
The page provides a comprehensive list of isomers of dodecane, including their chemical structures and properties.
2-Methyl-3-pentanol (IUPAC name: 2-methylpentan-3-ol) is an organic chemical compound. It is a secondary alcohol [2] that is used as a fuel. [3] References
1,5-Pentanediol is the organic compound with the formula HO(CH 2) 5 OH. Like other diols , this viscous colourless liquid is used as plasticizer and also forms polyesters that are used as emulsifying agents and resin intermediates.
