2-Bromobutane is an isomer of 1-bromobutane. Both compounds share the molecular formula C 4 H 9 Br. 2-Bromobutane is also known as sec -butyl bromide or methylethylbromomethane. Because it contains bromine , a halogen, it is part of a larger class of compounds known as alkyl halides .
Bromobutane (molecular formula: C 4 H 9 Br, molar mass: 137.02 g/mol) may refer to either of two chemical compounds: 1-Bromobutane (n-butyl bromide)
1-Bromobutane is the organobromine compound with the formula CH 3 (CH 2) 3 Br. It is a colorless liquid, although impure samples appear yellowish. It is insoluble in water, but soluble in organic solvents. It is primarily used as a source of the butyl group in organic synthesis. It is one of several isomers of butyl bromide.
The molecular formula C 4 H 9 Br, (molar mass: 137.02 g/mol, exact mass: 135.9888 u) may refer to: 1-Bromobutane; 2-Bromobutane; tert-Butyl bromide;
Bromopentanes are a group of bromoalkanes consisting of pentane isomers with one or more hydrogen atoms replaced by bromine atoms. They have the formula C 5 H 12–n Br n, where n = 1–12 is the number of bromine atoms. They are colorless liquids.
For example, the two hydrogen atoms of the CH 2 moiety in (S)-2-bromobutane are diastereotopic. Replacement of one hydrogen atom (colored blue) with a bromine atom will produce (2S,3R)-2,3-dibromobutane. Replacement of the other hydrogen atom (colored red) with a bromine atom will produce the diastereomer (2S,3S)-2,3-dibromobutane.
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
