Q: What type of hydrocarbons contain at least one double or triple bond between carbon atoms? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - ionic - catalytic - saturated - unsaturated A:
unsaturated
