Pentyl is a five- carbon alkyl group or substituent with chemical formula -C 5 H 11. It is the substituent form of the alkane pentane . In older literature, the common non-systematic name amyl was often used for the pentyl group. Conversely, the name pentyl was used for several five-carbon branched alkyl groups, distinguished by various prefixes.
1-Bromopentane or amyl bromide is a bromoalkane and isomer of bromopentane. It is a colorless liquid. It is found as a natural product in Fucus vesiculosus. Preparation. Most 1-bromoalkanes are prepared by free-radical addition of hydrogen bromide to the 1-alkene, which is 1-pentene in the case of 1-bromopentane.
Infobox references. 1-Bromopropane ( n-propylbromide or nPB) is an organobromine compound with the chemical formula CH 3 CH 2 CH 2 Br. It is a colorless liquid that is used as a solvent. It has a characteristic hydrocarbon odor.
Alkyl group. In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −CnH2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula ...
A bromide ion is the negatively charged form ( Br−) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
Neopentyl alcohol was the first described in 1891 by L. Tissier, who prepared it by reduction of a mixture of trimethyl acetic acid and trimethylacetyl chloride with sodium amalgam. [4] Neopentyl alcohol can be converted to neopentyl iodide by treatment with triphenylphosphite / methyl iodide: [5] (CH 3) 3 CCH 2 OH + [CH 3 (C 6 H 5 O) 3 P] + I ...
Butyl group. In organic chemistry, butyl is a four- carbon alkyl radical or substituent group with general chemical formula −C4H9, 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: The second isomer of butane, isobutane, can also ...
Amyl alcohols are alcohols with the formula C 5 H 11 OH. [1] Eight are known. A mixture of amyl alcohols (also called amyl alcohol) can be obtained from fusel alcohol. Amyl alcohol is used as a solvent and in esterification, by which is produced amyl acetate and other products. The name amyl alcohol without further specification applies to the ...
