Write the name and general formula of a chain of hydrocarbons in which an 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.

Answer»

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

NameGeneral Formula
AIkeneCnH2n
AlkyneCnH2n-2

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 a hydrocarbon.
(ii) Addition of hydrogen should be carried out in the presence of catalysts such as nickel or platinum.
Chemical Equation :
CH2=CH2+H2+(Ni or Pt)  → CH3-CH3 
Ethe                                               Ethane  
CH ≡CH +2H2+(Ni or Pt)  → CH2=CH2  
Ethyne                                    Ethene
