Answer the following question given this paragraph: Saturated hydrocarbons contain only single bonds between carbon atoms. They are the simplest hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in Figure below . Each carbon atom is bonded to three hydrogen atoms in this compound, which is named ethane. Q: What are the simplest hydrocarbons? Choices: - unsaturated hydrocarbons - complex carbohydrates - fossil fuels - saturated hydrocarbons A:
saturated hydrocarbons
