Question: 1 / 400

Which type of hydrocarbons contains only single bonds?

Unsaturated hydrocarbons

Aromatic hydrocarbons

Saturated hydrocarbons

Saturated hydrocarbons are characterized by containing only single bonds between their carbon atoms. This means that each carbon atom is bonded to the maximum number of hydrogen atoms possible, resulting in a fully "saturated" structure. Common examples of saturated hydrocarbons include alkanes, such as methane and ethane.

In contrast, unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms, which means they can bond with fewer hydrogen atoms. Aromatic hydrocarbons, such as benzene, feature alternating double bonds, and cyclic hydrocarbons may contain both single and multiple bonds depending on the structure. Thus, the defining feature of saturated hydrocarbons is their exclusive use of single bonds, making them the correct answer.
