Answer the following
A) Why micelle formation does take place when soap is added to water?
B) Explain combustion reaction and ethanol?
C) Name the compound CH3COOH and mention its functional group ?
Answers
A) Soap has two ends, one hydrophilic which has affinity for water and one hydrophobic which opposes water. Because of this, in water, soap molecules arrange in clusters such that the water loving hydrophilic part points out while the water hating hydrophobic part stays inside. These clusters are called micelles.
B) Combustion reaction is a exothermic reaction where an inflammable substance reacts with oxygen to give out heat energy. For example, methane burns in oxygen to give carbon dioxide and water along with heat and light.
Ethanol or C2H5OH is a type of alcohol which is used in most alcoholic drinks, beverages and medicines. It acts as a good solvent.
C) The compound is ethanoic acid or acetic acid. Its common name is vinegar.
The functional group is "carboxylic acid".
I hope these help. : )
