What is meant by the term “unsaturated hydrocarbon”? What structural feature characterizes

Interpretation:
The meaning of “unsaturated hydrocarbon” should be determined along with the structural features which characterizes unsaturated hydrocarbons.
Concept Introduction:
Compounds consist of carbon and hydrogen is known as hydrocarbons. Hydrocarbons are classified as saturated hydrocarbon and unsaturated hydrocarbon
Answer to Problem 1ALQ
The hydrocarbons in which carbon-carbon multiple bonds are present is said to be unsaturated hydrocarbons.
The unsaturated hydrocarbon which contains one or more double bonds in the structure is known as alkene whereas which contains one or more triple bonds in the structure is known as alkyne.
Explanation of Solution
Unsaturated hydrocarbons are those hydrocarbons in which carbon-carbon multiple bonds are present that is double and triple bond.
Unsaturated hydrocarbon which contains one or more double bond is known as alkenes and which contains one or more triple bonds are said to be alkynes.
Carbon atoms linked with double bond are bound with each other by one sigma and one pi bond and carbon atoms linked with triple bond are bound with each other by one sigma and two pi bonds.
For example:
The structure of alkene and alkyne is given as:
The hydrocarbons in which carbon-carbon multiple bonds are present is said to be unsaturated hydrocarbons.
The unsaturated hydrocarbon which contains one or more double bonds in the structure is known as alkene whereas which contains one or more triple bonds in the structure is known as alkyne.
