This compound is organic, aromatic, fused aromatic, and hydroxylic, among other descriptions.
The melting point of alpha naphthol is 95-96 oC.
At 20 oC it is solid
It creates a brownish liquid that makes an azo dye called Para Red when it is combined with a bright yellow mixture created from para-nitroaniline/HCl/sodium nitrite. So the reaction that you are talking about basically makes a brownish dye.
=In naphtalene ring, only carbon 1 and carbon 2 can be substituted to give monosubstituted product. So 1-naphhtol and 2-naphthol are the two monosubstituted alcohols (phenols) derived from naphthalene. So 2-naphthol has ONE isomer which is 1-naphthol.=
Yes
A-naphthol is a type of organic compound known as a naphthol, which is a phenol derivative. It consists of a naphthalene ring structure with a hydroxyl group attached at the alpha position. A-naphthol is commonly used in the production of dyes and pigments.
No, 2-naphthol is not soluble in hydrochloric acid (HCl) because it is a nonpolar compound and HCl is a polar solvent.
yes, it is much more soluble in ethanol than in water.
Phenyl azo beta naphthol is not a saturated compound. It contains multiple double bonds in its molecular structure, which makes it unsaturated.
The resonance structure of α-naphthol involves delocalization of electrons within the aromatic ring through the oxygen atom. This results in stabilization of the molecule due to electron delocalization, making the compound more stable.
alpha naphthol with CCl4(carbon tetrachloride) gives blue colour whereas beta naphthol with CCl4 gives no colour. that is the distinction test between alpha and beta naphthol.
Naphthol is typically produced as a red or yellow crystalline powder, depending on its chemical structure. The red form of naphthol is typically created from naphthol AS pigment, while the yellow form is produced from naphthol yellow dye.
Amino-naphthol sulfonic acid is a compound that is often used in the textile industry as a dyeing agent. It is a type of acid dye that can be applied to protein-based fibers like wool and silk. It is known for its ability to produce vibrant and colorfast dye shades.
The melting point of alpha naphthol is 95-96 oC.
At 20 oC it is solid
Yes, 2-naphthol is soluble in sodium hydroxide due to the formation of the sodium salt of 2-naphthol. Sodium hydroxide is a strong base that can deprotonate the hydroxyl group of 2-naphthol, leading to its solubility in the alkaline solution.
The melting point of phenylazo- beta-naphthol is somewhere from 131 to 133 degrees Celsius. Phenylazo- beta-naphthol is also called as Sudan I.
