What is the molecular mass of dichlorobenzene?
147.01 g/mol
1,2-Dichlorobenzene/Molar mass
What is the molecular formula of Paradichlorobenzene?
C6H4Cl2
1,4-Dichlorobenzene/Formula
1,4-Dichlorobenzene (1,4-DCB, p-DCB, or para-dichlorobenzene, sometimes abbreviated as PDCB or para) is an organic compound with the formula C6H4Cl2. This colorless solid has a strong odor. The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring.
What does p-Dichlorobenzene look like?
P-dichlorobenzene appears as a white colored liquid with the odor of moth balls. Denser than water and insoluble in water.
Why does p-Dichlorobenzene have zero dipole moment?
To determine which compound has zero dipole moment, we must study their respective molecular structures. From the above structures, we can observe that only p – Dichlorobenzene has the capacity to cancel out the charges on its constituents, because both the chlorine atoms are placed exactly opposite each other.

What is the dipole moment of 1/4-dichlorobenzene?
1, 4-dichlorobenzene will have no dipole moment, because it has symmetry. Chlorine groups are attached opposite sides that are why they will cancel each other dipole moments and hence they have zero dipole moment.
What is the dipole moment of p-dichlorobenzene?
zero
Answer: Dipole moment of p – dichlorobenzene is zero due to symmetrical structure.
Is para-dichlorobenzene volatile?
p-Dichlorobenzene (PDCB) is a chlorinated volatile organic compound (VOC) that can be encountered at high concentrations in buildings due to its use as pest repellent and deodorant.
What is the dipole moment of 1/2-dichlorobenzene?
2.50 D
The major difference is the range of dipole moments: 1,2-dichlorobenzene, 2.50 D; 1,3-dichlorobenzene, 1.72 D; and 1,4-dichlorobenzene, 0.00 D.
Which axis is are present in p-dichlorobenzene?
1,4-Dichlorobenzene D. 2h D2h point groups contain two C2 axes perpendicular to the main rotation axis with one σh plane.
Why does P-dichlorobenzene?
p-Dichlorobenzene has higher m.p. and lower solubility than those of o- and m-isomers. For this reason, it fits more closely than o-and m-isomers in the crystal lattice. Therefore, more energy is required to break the crystal lattice of p-dichlorobenzene.
What is the dipole moment of 1/2 dichlorobenzene?
What is the chemical formula for 1, 4 dichlorobenzene?
1,4-Dichlorobenzene (1,4-DCB, p-DCB, or para-dichlorobenzene, sometimes abbreviated as PDB or para) is an organic compound with the formula C6H4Cl2. This colorless solid has a strong odor. The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring.
How is 1, 4 dichlorobenzene harmful to humans?
1,4-dichlorobenzene is a dichlorobenzene carrying chloro groups at positions 1 and 4. It has a role as an insecticide. The primary exposure to 1,4-dichlorobenzene is from breathing contaminated indoor air. Acute (short- term) exposure to 1,4-dichlorobenzene, via inhalation in humans, results in irritation of the skin, throat, and eyes.
How is dichlorobenzene purified at room temperature?
The compound can be purified by fractional crystallization, taking advantage of its relatively high melting point of 53.5 °C; the isomeric dichlorobenzenes and chlorobenzene melt well below room temperature.
How big is a 1, 2 dichlorobenzene NMR tube?
1,2-Dichlorobenzene solution, NMR reference standard, 1% in acetone-d6 (99.9 atom % D), NMR tube size 3 mm x 8 in. 1,2-Dichlorobenzene solution, NMR reference standard, 5% in acetone-d6 (99.9 atom % D), NMR tube size 5 mm x 8 in. O-dichlorobenzene appears as a clear colorless liquid with a pleasant odor.
