Identify the molecular formula given: \(C_3H_8\).
Recall the general formulas for common classes of hydrocarbons: Alkanes have the formula \(C_nH_{2n+2}\), Alkenes have \(C_nH_{2n}\), and Alkynes have \(C_nH_{2n-2}\).
Check if the given formula fits the alkane formula by substituting \(n=3\): \(C_3H_{2(3)+2} = C_3H_8\).
Since the formula matches the alkane general formula exactly, conclude that the compound belongs to the alkane class.
Note that alcohols have the general formula \(C_nH_{2n+2}O\), which does not match the given formula without oxygen, so it is not an alcohol.
