As a result, other terms used to describe pentane include dimethylpropane, 2,2-dimethylpropane, and CH3(CH2)3CH3. Additionally, the word alkane is often used synonymously with pentane, as it is a member of the alkane family of hydrocarbons. Pentane is commonly used as a solvent in laboratories, as well as in the manufacturing of polystyrene foam and gasoline. Although the term pentane can sometimes be confusing, understanding its synonyms and uses can help clarify its meaning within the context of chemistry and science.
