P-dichlorobenzene appears as a white colored liquid with the odor of moth balls. Denser than water and insoluble in water.
Simply so, How do you pronounce Paradichlorobenzene?
How will you prepare 1/4 dichlorobenzene from chlorobenzene? When chlorobenzene reacts with chlorine and ferric chloride there is a formation of 1, 2- Dichlorobenzene or o- Dichlorobenzene and 1, 4- Dichlorobenzene or p- Dichlorobenzene. The reaction is given below: In this reaction 1, 4- Dichlorobenzene is the major product, and 1, 2- Dichlorobenzene is the minor product.
Subsequently, What is the difference between naphthalene and paradichlorobenzene?
Differentiation between naphthalene and paradichlorobenzene by odor or color is difficult. In an in vitro x-ray study, paradichlorobenzene was radiopaque but naphthalene was not visible. In a saturated salt solution (about 1 tablespoon of salt in 4 oz of water), naphthalene will float and paradichlorobenzene will sink.
Is Paradichlorobenzene a pure substance?
In this experiment you will observe the melting and freezing behavior of Para dichlorobenzene, a pure substance (commonly known as moth balls).
How many atoms are in dichlorobenzene? 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.
Is dichlorobenzene covalent or ionic?
P-dichlorobenzene is a covalent compound with carbon, hydrogen and chlorine atoms.
How is Paradichlorobenzene produced? Paradichlorobenzene is also known as 1,4-dichlorobenzene, paradichlorobenzol, p-DCB and PDB. It is produced by the chlorination reaction of benzene in the presence of iron (III) chloride as a synthesis catalyst.
Does isopropyl alcohol dissolve naphthalene?
1Wenty-five naphthalene and 25 paradichlorobenzene mothballs were weighed, randomly grouped, and then dissolved in the solvents. After 30 minutes, the mothballs were reweighed. Isopropyl alcohol, ethanol, and methanol did not differentially dissolve the mothballs fast enough to pro- vide a useful test.
Can I put mothballs in my garden? Mothballs should not be used inside attics, crawl spaces, gardens, trash cans or vehicles. Nor used to control skunks, mice or other pests. Mothballs should not be used inside attics, crawl spaces, gardens, trash cans or vehicles.
What are mothballs intended for?
The labeled use of mothballs is to kill moths and other fiber insects to protect clothing. To do so properly, place mothballs inside tightly closed containers along with the clothing or materials. The vapors will remain inside the container and kill the moths.
What does Paradichlorobenzene smell like? It is the whiff of mothballs, the aroma masking a damp basement, the essence of an under-ventilated bathroom. It comes from a solid brick of insect-chasing, odor-covering, toilet-bowl cleaning power called paradichlorobenzene — or « para » in the cleaning trade.
Is Paradichlorobenzene flammable?
* 1,4-Dichlorobenzene is a COMBUSTIBLE SOLID. * Use dry chemical, CO2, water spray, or a foaming agent. * POISONOUS GASES ARE PRODUCED IN FIRE, including Hydrogen Chloride. * CONTAINERS MAY EXPLODE IN FIRE.
What is the structure of meta dichlorobenzene?
1,3-Dichlorobenzene, also known as meta-dichlorobenzene, is an organic compound with the formula C6H4Cl2. It is the least common of the three isomers of dichlorobenzene, and it is a colorless liquid that is insoluble in water.
How do I get rid of dichlorobenzene? Chlorobenzene from the Product can be removed by extraction with ether as it is ether soluble.
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.
Does p-dichlorobenzene have a pKa?
1,4-dichlorobenzene dihydrodiol is soluble (in water) and a very weakly acidic compound (based on its pKa).
…

What is the structure of meta-dichlorobenzene? 1,3-Dichlorobenzene, also known as meta-dichlorobenzene, is an organic compound with the formula C6H4Cl2. It is the least common of the three isomers of dichlorobenzene, and it is a colorless liquid that is insoluble in water.
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.
What is the best solvent for naphthalene? It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and very soluble in ether, chloroform, or carbon disulfide.
Why is it called mothballs?
Even though they seem to be a general repellant, there is a reason they are called « moth » balls: they are specifically designed and labeled for moths. The purpose of this document is to provide the public with definitions and instructions for proper usage of mothballs.
Is naphthalene a liquid? OVERVIEW. Naphthalene (NAF-thuh-leen) is a white crystalline volatile solid with a characteristic odor often associated with mothballs. The compound sublimes (turns from a solid to a gas) slowly at room temperature, producing a vapor that is highly combustible.
