In this step of the experiment you are trying to separate benzoic acid from biphenyl an impurity. Sodium hydroxide reacts with benzoic acid to form (ar-O-O(-)na(+)) and (H2O), this allows for the ether layer containing biphenyl to separate as the precipitant, which we can now extract and discard.

Why is it necessary to extract ether layer with sodium hydroxide when reacting benzoic acid with hydroxide ion?

It depends on the overall reaction. If the carboxylic acid is an impurity in the reaction (undesired), then washing with sodium hydroxide will extract the carboxylic into the aqueous layer, and it can then be disposed. The reaction for this looks as follows: (ring)-COOH + NaOH -> (ring)-COO-Na+ + H20 Where the ring loses a proton to the hydroxide ion and becomes water soluble.


Will sodium chloride dissolve in diethyl ether?

No. Sodium chloride is polar, whereas diethyl ether is non-polar. Unlike solutes do not dissolve in unlike solvent. Only "like dissolves like".


How do you account for the observed solubility of naphthalene and sodium chloride in water and in ether based on the nature of the bonds that exist in them?

Naphthalene is nonpolar and therefore soluble in nonpolar solvents like ether, but not very soluble in the polar solvent water. Sodium chloride is ionic and soluble in water due to the strong ion-dipole interactions, but not soluble in ether which cannot stabilize the charged ions. The solubility of compounds in different solvents is primarily determined by the nature of the intermolecular interactions between the solute and solvent molecules.


What is reaction of 1-propanol with ethyl bromide?

The reaction between 1-propanol and ethyl bromide would result in an SN2 reaction where the ethyl bromide attacks the carbon bearing the -OH group on 1-propanol, displacing the hydroxyl group and forming ethyl propyl ether as the main product. Sodium hydroxide may be used as a catalyst in this reaction.


Is ethyl acetate or diethyl ether is same?

No, ethyl acetate and diethyl ether are not the same. Ethyl acetate is an ester commonly used as a solvent, while diethyl ether is an ether used as a solvent and a reagent in chemical reactions. They have different chemical structures and properties.

Is sodium bicarbonate soluble in ether?

No, sodium bicarbonate is not soluable in ether.


Is NaOH soluble in ether?

Classification of any substance as solute and solvent is not possible until it is being used along with other substance/s . The substance present in the largest quantity is solvent whereas substances present in smaller quantity which are able to get dissolved in the solvent are solute.

Is sodium metal is insoluble in ether a chemical or physical reaction?

Sodium metal being insoluble in ether is a physical property, not a chemical reaction. This is because no new substances are being formed, it is simply a case of the sodium metal not dissolving in the ether due to differences in polarity.

Why doesn't diethyl ether react with sodium?

Sodium ions react with other ionic species via electrostatic interactions. Diethyl ether does not contain any ionic functional groups, nor does it have acidic protons.
