1,2-Dichlorobenzene, or orthodichlorobenzene (ODCB), is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2. This colourless liquid is poorly soluble in water but miscible with most organic solvents. It is a derivative of benzene, consisting of two adjacent chlorine atoms.
Typical dipole moments for simple diatomic molecules are in the range of 0 to 11 D. Molecules with symmetry point groups or containing inversion symmetry will not have a permanent dipole moment, while highly ionic molecular species have a very large dipole moment, e.g. gas-phase potassium bromide, KBr, with a dipole moment of 10.41 D. [3] A proton and an electron 1 Å apart have a dipole ...
1,2-Dichlorobenzene or ortho-dichlorobenzene; 1,3-Dichlorobenzene or meta-dichlorobenzene; 1,4-Dichlorobenzene or para-dichlorobenzene. All three isomers are colorless chlorobenzenes with the formula C 6 H 4 Cl 2. They differ structurally based on where the two chlorine atoms are attached to the ring.
The polarizability of an atom or molecule is defined as the ratio of its induced dipole moment to the local electric field; in a crystalline solid, one considers the dipole moment per unit cell. [1] Note that the local electric field seen by a molecule is generally different from the macroscopic electric field that would be measured externally.
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
The work of Adams, et al. (1979) showed that the reaction field produces results with thermodynamic quantities (volume, pressure and temperature) which are in good agreement with other methods, although pressure was slightly higher with the reaction field method compared to the Ewald-Kornfeld method (1.69 vs 1.52).
The molecular formula C 6 H 4 Cl 2 (molar mass: 147.00 g/mol) may refer to: 1,2-Dichlorobenzene; 1,3-Dichlorobenzene; 1,4-Dichlorobenzene;
This is equivalent to 1 debye-ångström, where 1 debye = 10 −18 statcoulomb-centimetre is the CGS unit of molecular dipole moment and 1 ångström = 10 −8 cm. One buckingham corresponds to the quadrupole moment resulting from two opposing dipole moments of equal magnitude of 1 debye that are separated by a distance of 1 ångström, a ...
