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.
Name and general formula of hydrocarbons undergoing addition reaction are:
Name
General formula
Alkene
CnH2n
Alkyne
CnH2n-2
Essential conditions required for the addition reaction to occur are:
i) The presence of multiple bonds (double and triple bonds) between carbon atoms in the chain of a hydrocarbon.
ii) The addition of hydrogen should be carried out in the presence of a catalyst such as Nickel or platinum.
Chemical equation involved is:
CH2=CH2+h2------>CH3--CH3
The reactant is Ethene and the product formed is Ethane.
