How does benzoic acid form dimer in toluene layer?
Benzoic acid can form dimers in a toluene layer due to hydrogen bonding between the carboxylic acid groups of adjacent molecules. The aromatic ring structure of benzoic acid allows for efficient packing in the toluene layer, promoting dimer formation. This dimerization process is driven by the favorable interactions between the molecules, such as hydrogen bonding.
How do you separate benzoic acid from a mixture of benzoic acid and toluene using extraction?
Make a solution of Sodium Hydroxide or Sodium Carbonate and do three to four solvent solvent extractions using the aqueous base and the mixture o benzoic acid and toluene. Because benzoic acid reacts with base to form the water soluble carboxylate ion, it will react and the dissolve in the aqueous solution. Upon separation of the two phases acidify the aqueous extract with dilute HCl, a white needle-like precipitate of benzoic acid will form when the solution becomes acidic. Simply filter the crystals, wash with cold water, and then recrystallize using a mixture of 50/50 water and methanol or some other suitable solvent.
What happens when toluene is treated with alkaline KMnO4?
When toluene is treated with alkaline KMnO4, it undergoes oxidation. Toluene is converted to benzyl alcohol, and further oxidation can convert benzyl alcohol to benzoic acid. The purple color of the KMnO4 solution will fade as the reaction proceeds.
Acidified potassium permanganate reaction with toluene equation?
The reaction between acidified potassium permanganate and toluene results in the oxidation of toluene to benzoic acid. The balanced chemical equation for this reaction is: C7H8 + 2KMnO4 + 8H2SO4 → 2MnSO4 + K2SO4 + 7H2O + 7H2O + C6H5CO2H
What will happen if toluene react with potassium per magnate in presence of sodium carbonate?
When toluene reacts with potassium permanganate in the presence of sodium carbonate, the permanganate will oxidize the toluene to form benzoic acid. The sodium carbonate will help neutralize any acidic byproducts formed during the reaction.
Process of preparation of benzoic acid?
Benzoic acid is produced from toluene and oxygen. The toluene is oxidyzed and a water molecule is released, which resuls in benzoic acid source: wikipedia
Why toluene does not react with acidic or alkaline permanganates?
Toluene reacts with acidic permanganate on heating and forms the Benzoic acid.

Where does sodium benzoate come from?
Sodium benzoate is manufactured by reacting benzoic acid with sodium hydroxide. Benzoic acid is produced by partial oxydation of toluene with oxygen. There are half a dozen ways or more ways to make toluene.
Will toluene and benzoic acid react?
Toluene and benzoic acid can react together in the presence of a suitable catalyst, such as a strong acid or base, to form benzyl benzoate. However, without a catalyst, their reactivity towards each other is very low.
Acidified potassium permanganate reaction with toluene equation?

Why is hydrochloric acid added in a molar absorptivity of benzoic acid?
Hydrochloric acid is added to benzoic acid to convert it into its water-soluble salt form, sodium benzoate. This transformation allows for the benzoate ions to be detected and measured accurately in spectrophotometric analysis, which helps determine the molar absorptivity of benzoic acid.
Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.
What is the solubility of Benzoic acid in acetone?
Solubility of benzoic acid in acetone is 1.350 M
