A student measures the equilibrium vapor pressure of four pure liquid 1-alkanols at \(25\ ^\circ\text{C}\): methanol (\(\text{CH}_3\text{OH}\)), ethanol (\(\text{C}_2\text{H}_5\text{OH}\)), 1-propanol (\(\text{C}_3\text{H}_7\text{OH}\)), and 1-butanol (\(\text{C}_4\text{H}_9\text{OH}\)). Which of the following lists the compounds in order of decreasing vapor pressure (greatest to least) at \(25\ ^\circ\text{C}\) and provides the correct justification?
