Is P-dichlorobenzene a solid?
1,4-Dichlorobenzene (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.
What type of solid is Paradichlorobenzene?
Physical / Chemical Properties: Paradichlorobenzene is a colorless to white solid crystal with a strong pungent odor. It will sublimate, turning from a solid directly into a gas, at room temperatures.
Is 1 4-dichlorobenzene a solid a liquid or a gas at room temperature?
1,4-Dichlorobenzene is a colorless to white combustible crystalline solid at room temperature that slowly vaporizes when exposed to air and has a penetrating, mothball-like odor.

Is dichlorobenzene neutral?
1,4-Dichlorobenzene, also known as para-dichlorobenzene or p-dichlorobenzene, is a neutral, colourless, flammable solid (U.S. EPA, 1986) with a molecular weight of 147.01 and the empirical formula C6H4Cl2.
What is the use of dichlorobenzene?
p-Dichlorobenzene (PDCB) is a chlorinated volatile organic compound (VOC) that is widely used in essentially pure form (>99.8%) as a repellant against snakes, rats, mice, squirrels, bats and insects, as a deodorizer for toilets, urinals and diaper pails, as an insecticidal fumigant, and as an air freshener (National …
Is Paradichlorobenzene ionic or covalent?
Paradichlorobenzene does have a lower melting point, however this is because PDCB has a non-polar bond so it has London Forces for intermolecular bond, which are weaker than ionic bonds. It has a covalent intramolecular bond but intramolecular forces do not affect melting point, only intermolecular forces do.
Is Paradichlorobenzene flammable?
Flammable Properties Not flammable.
Is P-dichlorobenzene liquid?
Material is a solid at room temperature that melts upon moderate heating into a combustible liquid with a flash point below 200°F(93.3°C).
What is P-dichlorobenzene used for?
What type of solid is c6h4cl2?
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.
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 can p-dichlorobenzene be used for?
p-DICHLOROBENZENE. It is used mainly as an insecticidal fumigant against moths, as a space deodorizer, as a general insecticide and fungicide on crops, and as a chemical intermediate for plastics, dyes, pharmaceuticals and other organic compounds. All they are insoluble in water and denser than water.
What makes p-dichlorobenzene insoluble in water and denser than water?
p-DICHLOROBENZENE. All they are insoluble in water and denser than water. They are prepared by the chlorination reaction of benzene in the presence of iron (III) chloride. (the chlorination under strong illumination and without iron (III) chloride leads to benzene hexachloride instead of mono or polychlorobenzenes).
What happens when 1, 4 dichlorobenzene is heated?
When 1,4-dichlorobenzene is heated to decomposition, toxic gases and vapors (such as hydrochloric acid and carbon monoxide) are released. The primary route of potential human exposure to this compound is inhalation. Acute inhalation exposure to 1,4-dichlorobenzene can result in coughing and breathing difficulties.
What are the physical properties of paradichlorobenzene?
Physical / Chemical Properties: Paradichlorobenzene is a colorless to white solid crystal with a strong pungent odor. Vapor pressure: 4 x 10-1 mmHg at 20 °C Octanol-Water Partition Coefficient (log Kow) (unitless): 3.52 Henry’s constant (atm·m3/mol): 1.74 x 10-3 to 2.63 x 10-3 Molecular weight (g/mol): C6H4Cl2 = 147.0
