What is esterification reaction? Also write its equation.

When primary alcohol is treated with a carboxylic acid in the presence of sulphuric acid a compound is formed. This compound has a sweet smell. The compound obtained is called an ester. The chemical reaction occurring in the formation of the ester is known as an esterification reaction. CH 3 COOH + C 2 H 5 OH → conc . H 2 SO 4 CH 3 COOC 2 H 5 + H 2 O Acetic acid Ethanol Ethyl ethanoate ( Ester )

Draw the structure of the compound of carbon given below. Chloropropane.

Choropropane is a colourless, flammable chemical compound. It is a saturated straight chain carbon compound with one of the hydrogen atoms is substituted by a chlorine atom in propane. It has a chemical formula C 3 H 7 Cl , and is prepared by reacting n-propyl alcohol with phosphorous trichloride in the presence of zinc chloride catalyst. It has two isomers.

Draw the structure of the compound of carbon given below. Benzene.

Benzene is an organic chemical compound with a molecular formula C 6 H 6 . The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen attached to each with alternate double bonds. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.

Write preparation of ethanoic acid with chemical equation and also two uses of ethanoic acid.

Most acetic acid is produced by methanol carbonylation. In this process, methanol and carbon monoxide react to produce acetic acid according to the equation: H 3 C - OH + CO → catalyst Uses: 1. Commercially it is used in the manufacturing of esters, vinegar, and many polymeric materials. 2. Vinegar has been shown to reduce high concentrations of blood sugar in our body.

Write four properties of methane.

1. Methane is colourless, odourless gas that occurs abundantly in nature. 2. Methane is lighter than air, having a specific gravity of 0.554. 3. It is only slightly soluble in water. 4. It burns readily in the air, forming carbon dioxide and water vapour. C 2 H 4 + 2 O 2 → CO 2 + 2 H 2 O
