Q.Explain the mechanism of the cleaning action of soaps.

Solution : Many impurities and dirt are mixed in the water, and most of all the dirt does not dissolve in the water. Soap molecules are a combination of salts such as sodium or potassium. The molecules are of a long chain of salt of fatty acids. So, when the carbon chain is dissolved in …

Q. Give a test that can be used to differentiate between saturated and unsaturated hydrocarbons.

Solution: Bromine water test – Bromine water is used to differentiate between unsaturated compounds (like alkenes and alkynes) and saturated compounds. For this purpose, bromine is used in the form of bromine water. A solution of bromine in water is called bromine water. Bromine water has a red-brown colour due to the presence of bromine …

Q.What is hydrogenation? What is its industrial application?

Solution: Hydrogenation of oil : long fatty acids of Unsaturated hydrocarbons add hydrogen in the presence of catalysts such as palladium or nickel to give saturated hydrocarbons.This reaction is commonly used in the hydrogenation of vegetable oils using a nickel catalyst. Vegetable oils generally have long unsaturated carbon chains while animal fats have saturated carbon chains.You must have …
