2-Naphthol/Density

Does 2-naphthol react with NaOH?

2-napthol has acidic H on OH group which can react with base NaOH .

Is Alpha naphthol soluble in NaOH?

NaOH. Naphthols are insoluble in water and have no affinity for cellulosics. NaOH converts these into sodium salt of naphthols, called naphtholates, which are soluble and show affinity for cellulose.

What does 2-naphthol dissolve in?

Both isomers are soluble in simple alcohols, ethers, and chloroform. 2-Naphthol is a widely used intermediate for the production of dyes and other compounds.

Why do we add NaOH to the 2-naphthol before adding the electrophile?

If SN1 occurs instead of SN2, then the carbocation could rearrange and give an undesirable side product. Why is naphthol mixed with NaOH before adding the electrophile? Naphthol must be deprotonated by NaOH to make it a good nucleophile to react with the electrophile.

Is 2-naphthol soluble in acetone?

2,7-Naphthalenediol (2,7-Dihydroxynaphthalene), C10H8O2—160.17 [582-17-2]—Off-white to yellow, crystalline solid or powder. Dissolves in acetone. Melting range 741 : between 187 and 191 . 2-Naphthol (Betanaphthol), C10H7OH—144.17 [135-19-3]—White leaflets or crystalline powder.

Is nahco3 acidic or basic?

Sodium bicarbonate is a weak base with pH slightly above 7.

Is 3 Nitrobenzoic an acid or base?

The literature values1 for 3-nitrobenzoic acid was 140-142 °C, while that of the 4-nitro isomer was 239-241 °C. From this information it was concluded that our compound was 3-nitrobenzoic acid.

What is the pH of 2-naphthol?

9.5
GCB adsorbed 2-naphthol similarly from acidic and neutral solutions. This might be caused by the absence of any dissociable functional groups on both the adsorbate and adsorbent[4] in the pH range 2-7; the dissociation constant, pKa, for 2-naphthol is 9.5.

Is 2-naphthol an acid or base?

2-naphthol is weakly acidic with a pKa of 9.5. Unlike the other two compounds in the mixture, naphthalene is neutral.

Why do we dissolve 2 Naphthol in 10% NaOH?

Which simply means that the 10% NaOH would help extract organic solution for example, when making dye, by ionising the weak acid of organic compounds, (in this case 2-naphthol, C10H8O) in to salt and water. 2-naphthol is slightly soluble in water, but dissolves more readily in a basic solution because it is a weak acid.

What kind of alcohol is 2-naphthol soluble in?

Both isomers are soluble in simple alcohols, ethers, and chloroform. 2-Naphthol is a widely used intermediate for the production of dyes and other compounds.

Which is the correct formula for 2 Naphthol?

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.

What is the acid dissociation constant of 2-napthol?

The pK a of 2-napthol in the ground state was 9.47 compared to the lowest excited singlet state pK a * of 2.97. Both the ground and excited state acid dissociation constants correlated with literature values with a 0.2 and 1.0% difference, respectively.
