Naphthalene is an organic compound with formula C 10 H 8. 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. [15] As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings.
1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH. It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol. Both isomers are soluble in simple organic solvents. They are ...
Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic, and inorganic chemistry. It is usually generated in situ. When isolated, it invariably crystallizes as a solvate with ligands bound to Na +. [1]
The naphthalene route (the Gibbs phthalic anhydride process or the Gibbs–Wohl naphthalene oxidation reaction) has declined relative to the o-xylene route. Proposed early steps in vanadium -catalyzed oxidation of naphthalene to phthalic anhydride, with V 2 O 5 represented as a molecule versus its true extended structure.
2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) crystalline solid with the formula C 10 H 7 OH. It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol, but more reactive.
It is almost insoluble in cold water, slightly soluble in petroleum ether, and more soluble in polar organic solvents. In alkaline solutions it produces a reddish-brown color. Vitamin K is a derivative of 1,4-naphthoquinone. It is a planar molecule with one aromatic ring fused to a quinone subunit. [2] It is an isomer of 1,2-naphthoquinone.
1-Naphthoic acid is an organic compound with the formula C 10 H 7 CO 2 H. It is one of two isomeric mono carboxylic acids of naphthalene , the other one being 2-naphthoic acid . In general the hydroxynaphthoic acids are more widely used than the parent naphthoic acids.
The structure of sodium chloride, showing octahedral coordination around Na + and Cl − centres. This framework disintegrates when dissolved in water and reassembles when the water evaporates. Sodium compounds are of immense commercial importance, being particularly central to industries producing glass, paper, soap, and textiles. [6]
