In reaction (i) H2O molecule added to alkene and formation of ethanol, which is a example of hydration reaction.
In reaction (ii) one H2 molecule add with ethylene formation of ethane. The reaction where H2 reacts with a compound in presence of Pd catalyst is called hydrogenation reaction.
In reaction (iii) Cl2 molecule add to ethylene formation of dichloro compound. This type of halogen addition reactions are termed as halogenation reaction.
In reaction (iv) 3 ethyne molecule act as a monomer unit, which combine and forming cyclic benzene molecule. So, this type of reaction where joining of molecule and forming products is called polymerisation reaction.
