The most common use of naphthalene in consumer products is in the production of mothballs. It is a procedure. Let's go over some of the chemistry behind this compound. E C 2 (z) C 2 (y) C 2 (x) i (xy) (xz) (yz) Examples. It is a white solid. Friedel-Crafts acylation of naphthalene using benzoyl chloride, catalyzed by AlCl3, must be conducted above the melting point of the mixture, or the reaction may be violent [Clar, E. et al., Tetrahedron, 1974, 30, 3296]. The group has 8 irreducible representations. - Definition & Examples, What is an Aromatic Compound? - Uses, Structure & Production, What is Mercaptopurine? Each carbon atom (point) has a total of four bonds (lines connecting to it). Alkylated Naphthalenes for … Naphthalene is an organic compound with formula C10H8. β The S 8 point group could also be named C 8i, because the S 8 axis is identical to a roto-inversion axis of order 8. - Definition, Properties & Examples, What is Furfural? This is also where it gets the name white tar from, given its color and where it's derived from. - Uses & Overview, Anthracene: Lewis Structure, Formula & Resonance, Fluorenone: Structure, Solubility & Polarity, Fluorene: Polarity, Structure & Solubility, Alpha Beta Unsaturated Ketone: Formation & Reduction, What are Hydrogenated Fats? Chem. 115 – 135°C PAN Alkylated naphthalenes can aid in solubilizing additives in non-polar base stocks . A sheet of typing paper has three perpendicular C2 axes and three perpendicular mirror planes. Naphthalene is also known as napthene, naphthalin, camphor tar, and white tar. (6,7) Physical Properties The chemical formula for naphthalene is C10H8, and its molecular weight is 128.19 g/mol. Cs j. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. That's because that In this structure, each carbon atom shares at least one single bond with an adjacent carbon atom and one double bond with another carbon atom. 85 – 105°C . The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present, such as carboxylic acids (acidic) and amines … and career path that can help you find the school that's right for you. Type of representation general 3N vib. Sciences, Culinary Arts and Personal MAN -7 – 5°C . Electrical conductivity. point group of the molecule is D2h. It crystallizes into a white solid with a very noticeable coal-tar odor. - Structure, Formula & Isomers, What is Pentanol Used For? D2h. Naphthalene ingestion can result in acute as well as delayed toxicity. The naphthols are naphthalene homologues of phenol, with the hydroxyl group being more reactive than in the phenols.Both isomers are soluble in simple alcohols, ethers, and chloroform. A solution containing 2.0g of impure Naphthalene and 25mL of Methanol was prepared in a 50-mL Erlenmeyer flask. (1) Naphthalene occurs as a white solid or powderthat is insoluble in water. There is no definite point it varies. - Formula & Properties, Sodium Thiosulfate: Preparation, Risks & Uses, Sodium Thiosulfate & Hydrochloric Acid Experiment, What is Triazine? Its melting point is 80.2 degrees C, and its boiling point is 217.9 degrees C. It has a molecular weight of 128.174 g/mol. - Structure, Uses & Formula, Valence Bond Theory of Coordination Compounds, What is Benzene? | {{course.flashcardSetCount}} The primary target organs of toxicity are the blood and the eyes.
