Question

what are hydrocarbon?write the name and the general formula of (i) saturated hydrocarbons, (ii) unsaturated hydrocarbons, and draw the structure of one hydrocarbons of each type.how can an unsaturateds hydrocarbon be made saturated?

Answer 1

the compound consist of hydrogen and carbon are called hydrocarbon

saturated hydrocarbon. is Alkane
It's formula is Cn H2n+2

Unsaturated hydrocarbon are of two type
1 Alkene. It's formula is Cn H2n
2 Alkyne It's formula is Cn H2n-2

saturated hydrocarbon like Ethane [ C2 H6]

CH3----- CH3

unsaturated hydrocarbon like Ethene [ C2 H4]

CH2----- CH2




Unsaturated hydrocarbon can be made saturated hydrocarbon by the process of Hydrogenation . In which Unsaturated hydrocarbon is added to hydrogen in the presence of Nickel or palladium as catalyst and is strongly heated to get saturated hydrocarbon
Ni
C2 H4 + H2 ======. C2 H6
