There are six structural isomers, each with the molecular formula C 6 H 4 Br 2 O, ... 3,5-Dibromophenol, 1,3-Dibromo-5-hydroxybenzene Structural formula: CAS Number:
Pentabromophenol, by contrast, has only one isomer because all five available ring positions on the phenol are fully brominated. Monobromophenol (3 positional isomers) 2-Bromophenol; 3-Bromophenol; 4-Bromophenol; Dibromophenol (6 positional isomers) 2,3-Dibromophenol; 2,4-Dibromophenol; 2,5-Dibromophenol; 2,6-Dibromophenol; 3,4-Dibromophenol; 3 ...
At room temperature, 2,4-dibromophenol is a solid with needle-like crystals. It melts at 38 °C (100.4 °F) and boils at 238.5 °C (461.3 °F). it has a molecular weight of 251.905 g/mol. It is soluble in water, ethanol, ether and benzene and slightly soluble in carbon tetrachloride. [1]
Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.
Similarly, it was shown that the HOMO-LUMO gap, and therefore the color, of a series of heptacatafusenes depends on the number of π-sextets. [5] Clar's rule has also been supported by experimental results about the distribution of π-electrons in polycyclic aromatic hydrocarbons, [ 7 ] valence bond calculations , [ 8 ] and nucleus-independent ...
Typically, the open-ring isomers are colorless compounds, whereas the closed-ring isomers have colors dependent on their chemical structure, due to the extended conjugation along the molecular backbone. Therefore, many diarylethenes have photochromic behavior both in solution and in solid state.
