Answer the following question given this paragraph: Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms. As a result, the carbon atoms are unable to bond with as many hydrogen atoms as they would if they were joined only by single bonds. This makes them unsaturated with hydrogen. Unsaturated hydrocarbons are classified on the basis of their bonds as alkenes, alkynes, or aromatic hydrocarbons. Q: What type of hydrocarbons contain at least one double or triple bond between carbon atoms? A:
Select from the following.
A). ionic;
B). catalytic;
C). saturated;
D). unsaturated;
Answer:
