1. Why is the conversion of ethanol to ethanoic acid an oxidation reaction?2. A mixture of oxygen and ethyne is burnt for welding. Can you tell whya mixture of ethyne and air is not used? |

Answer» 1. Addition of oxygen or removal of hydrogen or loss of electrons is known as oxidation. Conversion of ethanol to ethanoic acid involves two steps.First step includes formation of ethanal,in which removal of hydrogen from ethanol takes place. And in second step,ethanal is converted into ethanoic acid,which involves addition of oxygen.Thus this is oxidation reaction. 2.When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000°C because of complete combustion. This oxy-acetylene flame is used for welding. It is not possible to attain such a high temperature without mixing oxygen. This is the reason why a mixture of ethyne and air is not used.
