Four-carbon molecules are based on a skeleton made from four carbon atoms. They may be in a chain, branched chains, cycles or even bicyclic compounds C 4 H 4 isomers with CAS registry numbers
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) 2-Bromobutane ( sec -butyl bromide or methylethylbromomethane)

Carbon compounds are defined as chemical substances containing carbon. [1] [2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n-butane can connect in two ways, giving rise to two "-butyl" groups:
A CN bond is strongly polarized towards nitrogen (the electronegativities of C and N are 2.55 and 3.04, respectively) and subsequently molecular dipole moments can be high: cyanamide 4.27 D, diazomethane 1.5 D, methyl azide 2.17, pyridine 2.19. For this reason many compounds containing CN bonds are water-soluble.
2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium. When bromobutane is the precursor, the product is a homogeneous solution, consisting of a mixed cluster containing both LiBr and LiBu. 1-Fluorobutane can be obtained by reacting 1-bromobutane with potassium fluoride in ethylene glycol.
