Respuesta :
Among the given compounds, compounds (A), (C) & (D) are saturated hydrocarbons and compound (B) is an unsaturated hydrocarbon.
What is hydrocarbons?
Hydrocarbons are those compounds in which carbon atom is present in addition to the hydrogen atoms.
- Saturated compounds are those compounds in which only single bonds are present between two carbon atoms.
- Unsaturated compounds are those compounds in which double or triple bonds are present between two carbon atoms.
So, according to the data given in the question it is clear that compound (A), (C) and (D) are saturated compounds as in these only single bonds are present and compound (B) is an unsaturated compound because of the presence of the double bonds.
Hence only compound (B) is an unsaturated compound.
