Write the name and general formula of a chain of hydrocarbons in which ar addition reaction with hydrogen can take place Stating the essential conditions required for an addition reaction to occur, write the chemical equation giving the name of the reactant and the product of such a reaction.

Explanation

Name and general formula of hydrocarbons undergoing addition reaction with hydrogen :

Essential conditions required for the addition reaction to occur :
(i) Multiple bonds (double and triple bonds) must be present between carbon atoms in the chain of hydrocarbon.
(ii) Addition of hydrogen should be carried out in the presence of catalyst such as nickel or platinum.
Chemical Equation:
`underset("Ethene")(CH_(2))=CH_(2)+H_(2)overset"(Ni ot Pt)"rightarrow underset("Ethene")(CH_(3) - CH_(3))`
`underset("Ethene")(CH-)= CH+2H_(2)overset"(Ni ot Pt)"rightarrow underset("Ethene")(CH_(2))= CH_(2)`
