Which of the following compounds is an unsaturated hydrocarbon? (2023)

Step 1: Understand what a hydrocarbon is. A hydrocarbon is a compound made up of hydrogen and carbon atoms.
Step 2: Learn the difference between saturated and unsaturated hydrocarbons. Saturated hydrocarbons have only single bonds between carbon atoms, while unsaturated hydrocarbons have at least one double or triple bond.
Step 3: Look at the compound C2H4 (ethylene). Count the number of carbon atoms (2) and hydrogen atoms (4).
Step 4: Determine the type of bonds in C2H4. Since it has a double bond between the carbon atoms, it is classified as an unsaturated hydrocarbon.
Step 5: Conclude that C2H4 (ethylene) is an unsaturated hydrocarbon because it contains a double bond.
