Relative Boiling Points

The line formulas and names of eight similarly sized and shaped compounds are shown below. Other than hydrogen, they are all composed of five heavier second row atoms, have molecular weights in the 72 to 74 amu range and have from 40 to 42 electrons. The boiling points of these compounds range from 28º to 141 ºC.
Estimate the boiling point order by typing an appropriate number in the box below each name. (1 is highest boiling & 8 is lowest boiling).
