Phenacyl bromide is the organic compound with the formula C 6 H 5 C(O)CH 2 Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds. It is prepared by bromination of acetophenone: [2] C 6 H 5 C(O)CH 3 + Br 2 → C 6 H 5 C(O)CH 2 Br + HBr. The compound was first reported in 1871. [3]
Bromoacetone is an organic compound with the formula C H 3 COCH 2 Br. It is a colorless liquid although impure samples appear yellow or even brown. It is a colorless liquid although impure samples appear yellow or even brown.
Molar mass: 157.010 g·mol −1 Appearance Colourless liquid Odor: Pleasant aromatic odor Density: 1.495 g cm −3, liquid Melting point: −30.8 °C (−23.4 °F ...
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
The derived quantity relative molecular mass is the unitless ratio of the mass of a molecule to the atomic mass constant (which is equal to one dalton). [2] The molecular mass and relative molecular mass are distinct from but related to the molar mass.
From January 2008 to December 2012, if you bought shares in companies when Howard I. Atkins joined the board, and sold them when he left, you would have a -6.7 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
