QQuestion
Show with the help of the structural formula of ethylene that it is an unsaturated hydrocarbon.

Structural formula of ethylene (C₂H₄):
H₂C = CH₂
Ethylene contains a carbon-carbon double bond (C=C). Therefore, the valencies of carbon atoms are not fully saturated with hydrogen atoms.
Hence, ethylene is an unsaturated hydrocarbon.
