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.
183.7 °c (362.7 °f; 456.9 k) 184.5 °C (364.1 °F; 457.7 K) Benzyl bromide is an isomer, which has a bromine substituted for one of the hydrogens of toluene 's methyl group, and it is sometimes named α-bromotoluene.
Benzyl bromide is an organic compound with the formula C 6 H 5 CH 2 Br. The molecule consists of a benzene ring substituted with a bromomethyl group. It is a colorless liquid with lachrymatory properties. The compound is a reagent for introducing benzyl groups. [3] [4]
Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. [3]Bromobenzene is used to introduce a phenyl group into other compounds.
The LLV (also called Vortec 2900) is a 2.9 L; 178.3 cu in (2,921 cc) straight-4 DOHC engine produced between 2007 and 2012, with a 95.5 mm × 102 mm (3.76 in × 4.02 in) bore and a stroke. It replaced the LK5 and produced 185 hp (138 kW) at 5,600 rpm and 190 lb⋅ft (258 N⋅m) of torque at 2,800 rpm.
It undergoes the reactions typical for nitrobenzene derivatives, e.g. hydrogenation gives p-toluidine. Oxidation of the methyl substituent of 4-nitrotoluene has been extensively investigated. Depending on the conditions, oxidation yields 4-nitrobenzaldehyde diacetate, [6] 4-nitrobenzenoic acid, [7] and 4,4'-dinitrobibenzyl. [8]
