Rank the compounds in order of increasing boiling point:
a. CH₃(CH₂)₄I, b. CH₃(CH₂)₅I, c. CH₃(CH₂)₆I.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
The boiling point in this example depends on molar mass of the compounds.
The greater the molar mass of the compound, the greater is the boiling point.
M(CH₃(CH₂)₄I) = 197.9 g/mol; molar mass
M(CH₃(CH₂)₅I) = 211.9 g/mol
M(CH₃(CH₂)₆I) = 225.9 g/mol
The compound CH₃(CH₂)₆I has the greater molar mass, so it has the greatest boiling point.
