How naphthalene is formed?
In extreme astrochemical conditions, naphthalene and dihydronaphthalene can be formed in the C6H5 + vinylacetylene and C6H5 + 1,3-butadiene reactions, respectively. Ethynyl-substituted naphthalenes can be produced via the ethynyl addition mechanism beginning with benzene (in dehydrogenated forms) or with styrene.
What type of compound is naphthalene?
hydrocarbon compounds
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 is common name of naphthalene?
naphthalin
Naphthalene is also known as napthene, naphthalin, camphor tar, and white tar.
What is the structure of arene?
The arenes you are likely to encounter at this level are based on benzene rings. The simplest of these arenes is benzene itself, C6H6. The next simplest arene is methylbenzene (common name: toluene), which has one of the hydrogen atoms attached to the ring replaced by a methyl group – C6H5CH3.
Who discovered naphthalene?
Naphthalene, discovered in 1819 by A. Garden (BUA, 1989), is a natural constituent of coal tar and crude oil, which are major contributors to its presence in the environment. They contain up to 11% and 1.3% of the chemical, respectively (BUA, 1989; O’Neil et al., 2001).
What is arenes group?
Benzene and substituted benzenes As a functional group, benzene, substituted benzenes and polybenzenes are called “arenes”.
What is arenes family?
An arene or aromatic hydrocarbon is a hydrocarbon with alternating double and single bonds between carbon atoms forming rings. Benzene is an example of arenes. Arene may also refer to: Arene (gastropod), a genus of marine snails in the family Areneidae.
What is the common name for naphthalene?
Naphthalene is also known as napthene, naphthalin, camphor tar, and white tar.
What are the characteristics of arenes?
The arenes themselves generally are quite toxic; some are carcinogenic and inhalation of their vapors should be avoided. The volatile arenes are highly flammable and burn with a luminous sooty flame, in contrast to alkanes and alkenes, which usually burn with a bluish flame leaving little carbon residue.
What is the common use for naphthalene?
– Hemolytic anemia – this is where your red blood cells pop like a balloon. – Liver damage – Damage to the nervous system – Allergic skin reactions – Cataracts, thus limiting your ability to see
Is naphthalene toxic to humans?
The International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) concluded that naphthalene is possibly carcinogenic to humans. The U.S. EPA classified naphthalene as a possible human carcinogen, also based on animal studies. Has anyone studied non-cancer effects from long-term exposure to naphthalene?
What is naphthalene used in?
The following are some other uses for naphthalene which are still ongoing: Naphthalene is the primary ingredient in mothballs, which are used to preserve clothing. It is used in the polymers industry, especially in the manufacturing of resins and plastics.
