rank from highest to lowest boiling point. to rank items as equivalent, overlap them.

Hi, I have a question and I hope anyone could answer it:

Place these hydrocarbons in order of decreasing boiling point. Rank from highest to lowest boiling point. To rank items as equivalent, overlap them.

hexadecane, C16H34

paraffin, C25H52

octane, C8H18

2,2,4-trimethylpentane, C8H18

propane, C2H8

  1. Answer:

    The hydrocarbons can be arranged from their highest to lowest boiling points as follows:

    • Paraffin, C35H72=370oCC35H72=370oC
    • Hexadecane, C16H34=286.8oCC16H34=286.8oC
    • Pentane, C5H12=36oCC5H12=36oC
    • 2-2 dimethylpropane, C6H12=10oCC6H12=10oC
    • Methane, CH4=164oC
