Q.2) VERY SHORT ANSWERS.
1.) Soaps are the salts formed when oils and fats reacts with alkalies. They are esters of fatty acids and glycerol.
Detergents are cleansing agents made from hydrocarbons obtain from coal and petroleum.
2.) Some hydrocarbons with high molecular masses, when heated in absence of air undergo decomposition to form hydrocarbons with lower molecular masses , this process is called thermal cracking.
3.) When hydrocarbons burn they combine with the oxygen in the air to form CO2 and H2O along with heat and light. This process is called combustion.
4.) Polymerisation is the process in which a large number of simple molecules combine under suitable conditions to form complex molecule.
5.) A reaction in which an atom or a group in a compound is replaced by another atom or a group is called substitution reaction.
6.) Reactions in which unsaturated organic compounds with double bond or triple bonds react with other molecules to form saturated compounds are called addition reactions.
