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 convert toluene to benzoic acid?
Toluene can be oxidized to benzoic acid using a strong oxidizing agent, such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). The reaction typically occurs under acidic conditions. The methyl group of toluene is oxidized to a carboxylic acid group, resulting in the formation of benzoic acid.
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.
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 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.
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.
Why is benzoic acid is extracted into ether then extracted into an alkali solution prior to being precipitated with strong acid in its preparation with grignard reagent?
When you're attempting to extract benzoic acid from other organic compounds, it is necessary to change its pH by adding a layer of an basic compound such as 1M NaOH so that the benzoic acid then can be separated from the organic layer within a separatory funnel. When in NaOH, the benzoic acid loses a proton and thus becomes its conjugate base (the benzoate ion). The benzoate ion is charged and thus become miscible in the aqueous layer. To extract benzoic acid (ie get it to precipitate out of solution), a strong acid such as HCl must be added to solution. After the extraction, lower the pH of the solution, and recrystalize (use ice after the recrystalization to get benzoic acid crystals to crash out).

How do you determine the partition coefficient of benzoic acid between benzene and water?
To determine the partition coefficient of benzoic acid between benzene and water, you would first measure the concentrations of benzoic acid in each solvent layer after equilibrium is reached. Then, calculate the partition coefficient by dividing the concentration of benzoic acid in benzene by the concentration in water at equilibrium. This ratio represents how the compound distributes between the two solvents.
Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.
