Benzoic Acid Lewis Structure:Drawing And Detailed Explanations

In this article we will get to know about benzoic acid lewis structure, its synthesis, chemical and physical properties and its applications.

Benzoic acid is an organic molecule found in our food and cosmetic goods on a regular basis. Pickles, jams, lipsticks, wash creams, and other goods include it. This substance is a preservative. It is also a necessary precursor for several organic combination syntheses.

  3. Benzoic acid’s physical characteristics
  4. Benzoic acid’s chemical characteristics
  5. Benzoic acid’s use

The organic compound is benzoic acid, which has the chemical formula C6H5COOH. It is made up of a carboxylic group on the benzene ring. Benzoic acid’s aromatic carboxylic acid may thus be detected. In normal circumstances, the chemical is a white crystalline solid. C6H5COOH esters and salts are referred to by this name.

1. The structure of benzoic acid is as follows:

The empirical formula for C7H6O2 benzoic acid is C6H5COOH, while the molecular formula is C6H5COOH.

The carboxylic acid of benzene is also known as benzene. There are seven carbon atoms, two oxygen atoms, and six hydrogen atoms in each molecule. It is made up of a six-carbon ring with alternate single and double bands, as well as a –COOH group linked to the ring, which gives it the name benzoic acid.

2. Benzoic acid production:

Phenol is converted to benzoic acid in this step.

First, we use zinc dust to convert phenol to benzene, and then we use CH3Cl+AlCl3 to convert benzene to Toluene, with aluminium trichloride acting as a Lewis acid catalyst.

By oxidation, toluene is transformed to benzoic acid.

3. Benzoic acid’s physical characteristics:

Benzoic acid reaction appears uncoloured in its solid form of crystalline nature.

Its crystal structure is nonclinical.

Because of the aromatic ring, this chemical is mildly agreeable.

At 130oC, the density of this chemical drops to 1,075 grammes per cubic centimetre.

The melting point of benzoic acid is 122.30 degrees Celsius.

The molar mass of benzoic acid is 122.12 g/mol.

4. Benzoic acid’s chemical characteristics:

At temperatures of 25°C and 100°C, the solubility is 3.44 g/L and 56.31 g/l, respectively.

Alcohol, benzene, carbon tetrachloride, and acetone are all soluble.

The pka dissociation constant of benzoic acid is 4.2.

It’s possible that the carboxyl group or perhaps the Aromatic Ring will be affected.

5. Benzoic acid’s use:

It is employed in an acidic media, but because it splits into ions in an alkaline medium, it loses its preservation action.

Benzoic acid, when used as a preservative, has no effect on the odour or flavour of food.

It prevents bacteria from reproducing by keeping their purity.

Because there is an amide link between the benzoate and the glycine that is discharged through the urinary tract, the benzoic acid sodium salt sodium benzoate lowers the blood level of glycine.

Benzoic acid esters can be used as plasticizers.

Benzoic acid and its sodium salt are employed as food preservatives in numerous foods such as soda, barbecue sauces, pickles, and dressings to inhibit the growth of germs and fungus.

Benzoic acid is used to treat a variety of skin irritations, including sunburns, insect bites, and fungal infections.

 It is utilised as a pH adjuster in the creation of scents, and it is employed especially in cosmetics.

It is mostly used in acidic foods because even at very low pH it has more anti-food and antibacterial properties.
