Solution Methylated spirits also known as Denatured alcohol or wood spirit or denatured rectified spirit. Methylated spirits contains 90% alcohol, 9% methanol and pyridine, CuSO4 etc. The additives in ethanol make it poisonous, and foul-smelling so avoid the consumption of alcohol. To avoid the high tax and regulations on drinking alcohol. Denatured alcohol was formed …
Solution Ethyl alcohol is called power alcohol because it is used to generate power for IC engines. It is also used as an additive to motor fuels to act as fuel for internal combustion engine. The Power alcohol is mixture of generally 80% petrol and 20 – 25 % alcohol.
Solution Ethanoic acid is commonly called acetic acid and belongs to a group of acids called carboxylic acids. 5-8% solution of acetic acid in water is called ‘vinegar.‘ It can be used to cook, bake, clean, and control weeds. It may also help with weight loss and lower cholesterol and blood sugar levels. It is …
Solution : Saponification On treating ester with an alkali, the ester is converted back to alcohol and sodium salt of carboxylic acid. This reaction is known as saponification . because it is used in the preparation of soap. Soaps are sodium or potassium salts of long chain carboxylic acid.
Difference between Soap and Detergent
SOAPS AND DETERGENTS Soap : The effect of soap on cleaning. Most dirt is oily and as you know, oil does not dissolve in water. The molecules of soap are sodium or potassium salts of long-chain carboxylic acids. The ionic end of soap interacts with the water while the carbon chain interacts with oil. The …
SOME IMPORTANT CARBON COMPOUNDS – ETHANOL AND ETHANOIC ACID Many carbon compounds are invaluable to us. But here we shall study the properties of two commercially important compounds – ethanol and ethanoic acid. Properties of Ethanol Ethanol is a liquid at room temperature . Ethanol is commonly called alcohol and is the active ingredient of …

Micelles Soaps are molecules in which the two ends have differing properties, one is hydrophilic, that is, it interacts with water, while the other end is hydrophobic, that is, it interacts with hydrocarbons. When soap is at the surface of water, the hydrophobic ‘tail’ of soap will not be soluble in water and the soap …
Substitution Reaction Saturated hydrocarbons are fairly unreactive and are inert in the presence of most reagents. However, in the presence of sunlight, chlorine is added to hydrocarbons in a very fast reaction. Chlorine can replace the hydrogenatoms one by one. It is called a substitution reaction because one type of atom or a group of …
Addition Reaction Unsaturated hydrocarbons add hydrogen in the presence of catalysts such as palladium or nickel to give saturated hydrocarbons. Catalysts are substances that cause a reaction to occur or proceed at a different rate without the reaction itself being affected. This reaction is commonly used in the hydrogenation of vegetable oils using a nickel …
