What is naphthalene in chemistry?

Naphthalene is a bicyclic aromatic hydrocarbon derived from coal tar or crude oil. ^1,2. It is an insecticide that is also used as a repellent. ³. Its International Union of Pure and Applied Chemistry (IUPAC) name is naphthalene.

What are naphthalene made of?

Naphthalene is made from crude oil or coal tar. It is also produced when things burn, so naphthalene is found in cigarette smoke, car exhaust, and smoke from forest fires. It is used as an insecticide and pest repellent.

What is naphthalene in organic chemistry?

naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C₁₀H₈.

What type of compound is naphthalene?

Naphthalene is a bicyclic aromatic hydrocarbon derived from coal tar or crude oil. It is an insecticide that is also used as a repellent. Its International Union of Pure and Applied Chemistry (IUPAC) name is naphthalene.

Is naphthalene same as camphor?

As nouns the difference between camphor and naphthalene is that camphor is (organic compound) a white transparent waxy crystalline isoprenoid ketone, with a strong pungent odour, used in pharmacy while naphthalene is a white crystalline hydrocarbon manufactured from coal tar; used in mothballs.

Naphthalene | Structure | Synthesis | Reactions | Uses | BP 301T | L~27

Why naphthalene is aromatic?

As we are getting a whole number from, 4nπ+2 formula for naphthalene, so naphthalene is aromatic. Therefore, the naphthalene is an aromatic compound according to Huckel's rule because it has 4nπ+2 delocalised electrons. Note: Pi bonds are known as delocalized bonds. Pi bonds cause the resonance.

Is naphthalene an acid or base?

Naphthalene, on the other hand, is a neutral organic compound, and therefore is not soluble in water or the aqueous solutions that will be produced throughout the experiment. It was located in the organic layer during the extraction process.

Is naphthalene a solute or solvent?

Because of its simplicity, naphthalene is a suitable solute with which to initiate the difficult study of solubility phenomena.

Is naphthalene a drug?

Naphthalene or mothballs, a commonly used substance in households and freely available in the market is an uncommon form of inhalant abuse which may lead to severe medical complications. We report an adolescent with addiction to naphthalene balls who developed severe anemia.

Is naphthalene a pure substance?

determination of a melting point, eg for naphthalene (pure substance) or candle wax (impure substance)

Is naphthalene harmful to humans?

Acute (short- term) exposure of humans to naphthalene by inhalation, ingestion, and dermal contact is associated with hemolytic anemia, damage to the liver, and neurological damage.

What color is naphthalene?

Naphthalene is generally white in color. It is also found in transparent to brownish color. The molecular weight of naphthalene is 128.18 g/mol. Naphthalene is insoluble in water at normal room temperature.

What is the pH of naphthalene?

Executive summary: The pH of 1,4-Naphthalenedicarboxylic acid at 10% in water is 3.6 (according to OECD 122 and DIN 19268:2007-05).

Is naphthalene soluble in water?

It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and very soluble in ether, chloroform, or carbon disulfide. Naphthalene is obtained from coal tar, a byproduct of the coking of coal.

Is naphthalene a liquid?

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.

Is naphthalene aromatic or not?

Naphthalene, with two fused rings, is the simplest polycyclic aromatic molecule. Note that all the carbon atoms except those at the points of fusion have a bond to a hydrogen atom. Naphthalene, which has 10 π electrons, satisfies the Hückel rule for aromaticity.

Is naphthalene a ketone?

2-acetylnaphthalene is a naphthyl ketone that is naphthalene substituted at position 2 by an acetyl group.

What is the uses of naphthalene?

Naphthalene is an aromatic hydrocarbon found in coal tar or crude oil. Naphthalene is used in the manufacture of plastics, resins, fuels, and dyes. It is also used as a fumigant insecticide that works by turning directly from a solid into a toxic vapor. This process is called sublimation.

Is naphthalene saturated or unsaturated?

Camphor and naphthalene unsaturated and alcohol is saturated. Naphthalene =unsaturated.

Is naphthalene banned?

3. Why is Naphthalene banned? The substance is banned due to its toxicity to humans, especially children, and its carcinogenic (cancer causing) properties. It is also highly flammable.

What are mouth balls?

Mothballs are small balls of chemical pesticide and deodorant, sometimes used when storing clothing and other materials susceptible to damage from mold or moth larvae (especially clothes moths like Tineola bisselliella).

Can we burn naphthalene balls?

No, naphthalene mothballs are not flammable, but they are combustible, just like 1,4-dichlorobenzene mothballs are. They can catch fire but the flashpoint is above 100 degrees Fahrenheit. They are considered an explosive hazard when in vapor form.

Is naphthalene covalent or ionic?

Naphthalene is a covalent molecule, because it is only consists of carbon-hydrogen bonds, but it is not a complex molecule. Carbon and hydrogen are nonmetals with similar levels of electronegativity.
