tert-Butyl bromide (also referred to as 2-bromo-2-methylpropane) is an organic compound with the formula Me 3 CBr (Me = methyl). The molecule features a tert-butyl group attached to a bromide substituent. This organobromine compound is used as a standard reagent in synthetic organic chemistry. It is a colorless liquid.
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 ...
3 replacing hydrogen atoms on carbon atoms 2 and 3. It is an alkane ("paraffin" in older nomenclature), a fully saturated hydrocarbon ; specifically, one of the isomers of heptane . Like typical alkanes, it is a colorless flammable compound; under common ambient conditions, it is a mobile liquid, less dense than water.
For esters such as ethyl acetate (CH 3 COOCH 2 CH 3), ethyl formate (HCOOCH 2 CH 3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The "-oate" changes to "-ate." Some simple examples, named both ways, are shown in the figure above.
Skeletal formula of 3-bromopentane: Van der Waals space filling model of 3-bromopentane: Names Preferred IUPAC name. 3-Bromopentane [1] Other names 3-Pentyl bromide.
3-Methylpentane is a branched alkane with the molecular formula C 6 H 14. It is a structural isomer of hexane composed of a methyl group bonded to the third carbon atom in a pentane chain. It is of similar structure to the isomeric 2-methylpentane , which has the methyl group located on the second carbon of the pentane chain.
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 ...
It is somewhat soluble in water and readily evaporates into the air. Bromoform is the main trihalomethane produced in beachfront salt water swimming pools with concentrations as high as 1.2 ppm (parts per million). Concentrations in freshwater pools are 1000 times lower. [9] Occupational skin exposure limits are set at 0.5 ppm. [10]
