Why certain compounds are called hydrocarbons? Write the general formula for homologous series of alkanes, alkenes and alkynes and also draw the structure of the first member of each series. Write the name of the reaction that converts alkenes into alkanes and also write a chemical equation to show the necessary conditions for the reaction to occur.
Certain compounds contain only carbon and hydrogen. Hence, these organic compounds are called hydrocarbons.
The general formula for the homologous series of alkanes = CnH2n+2 First member of the alkane family is methane.
The general formula for the homologous series of alkenes = CnH2n First member of the alkene family is ethene.
The general formula for the homologous series of alkynes = CnH2n-2 First member of the alkyne family is ethyne.
Catalytic hydrogenation is the reaction used to convert alkenes to alkanes.
