Monobromotoluene isomers [1] [2] [3]; Common name Structure Systematic name: 1-bromo-2-methylbenzene 1-bromo-3-methylbenzene 1-bromo-4-methylbenzene Molecular formula
The ratio between numbers of ortho and para molecules is about 3:1 at standard temperature where many rotational energy levels are populated, favoring the ortho form as a result of thermal energy. However, at low temperatures only the J = 0 level is appreciably populated, so that the para form dominates at low temperatures (approximately 99.8% ...

o-Toluidine (ortho-toluidine) is an organic compound with the chemical formula CH 3 C 6 H 4 NH 2. It is the most important of the three isomeric toluidines . It is a colorless liquid although commercial samples are often yellowish.
In 1963, Ortho introduced the second oral contraceptive available in the United States (Ortho-Novum 10 and Ortho-Novum 2, produced by Syntex). In 1964, Ortho bought rights to and marketed the Gynekoil (Margulies Coil) and Lippes Loop inert plastic IUDs in the United States until the mid-1970s and 1985, respectively.
1. Chocolate Fondue. Think of that fondue fountain at the buffet as Willy Wonka's sacred chocolate waterfall and river. The chocolate must go untouched by human hands, or it will be ruined.
We tried out the $600 tote from Drunk Elephant to see if it was worth it or just an expensive mistake.
The Fries rearrangement, named for the German chemist Karl Theophil Fries, is a rearrangement reaction of a phenolic ester to a hydroxy aryl ketone by catalysis of Lewis acids.
