Burning the members of groups 1 and 2 in air is not a suitable way to form the oxides of these elements. These metals are reactive enough to combine with nitrogen in the air, so they form mixtures of oxides and ionic nitrides. Several also form peroxides or superoxides when...
what is SO4 and why does it have a charge of -2? A small amount of liquid bromine is added to a container which is then sealed. Using the ideas of kinetic energy, can you explain why after one hour the bromine molecules have spread uniformly to occu ...

“Halogen” represents chlorine, fluorine, bromine or iodine.“Heterocycloalkyl” refers to a saturated or partially saturated monocyclic, bicyclic, or polycyclic ring containing at least one heteroatom selected from nitrogen, sulfur, oxygen, preferably from 1 to 3 heteroatoms in at least one ring....

a bromine group, and an iodine group, a hydroxy group, a carboxyl group, a cyano group, a nitro group, and a formyl group are mentioned, and furthermore, in any of above-mentioned substituent group, one or more hydrogen atoms thereof may be further substituted by above-mentioned other sub...
as a peroxygen activator, an aromatic sulfonyl fluoride of the formula ArSO2F wherein Ar is phenyl or naphthyl bearing 1 to 3 substituents selected from the class consisting of nitro, lower alkyl, benzamido, lower aliphatic carboxamido, chlorine, bromine, lower aliphatic acyl and lower alkoxyl....

By replacing chlorine with bromine in the precursor, synthesizing bromo analog 5 (Scheme 2), we showed that when it was treated with NaN3 under the conditions we found, compound 6 can be obtained in 95% yield in a shorter time (3 h). Scheme 2. Reagents and conditions: i, HNO3/Ac2O,...
Isoselenazolone 104 was found as an efficient catalyst in three reactions: the bromolactonization of alkenoic acids with bromine or N-bromosuccinimide (NBS) in the presence of potassium carbonate as base, the bromoesterification of alkenes using a variety of carboxylic acids, and the oxidation ...
