Question

Order the following compounds by boiling point-lowest boiling point first (1 point) 1) Hexane 2) 2-methylpentane 3) 2,2-dimethylbutane 4) 3-bromopentane 5) 2,3-dimethylbutane 6) 1-hexanol Order 7. Justify your order for the previous question (1 point)

Answer 1

Neither n-hexane nor 2,3-dimethylbutane is hydrogen bonded, so they will be next higher in boiling points. Because 2,3-dimethylbutane is more highly branched (and has a smaller surface area) than n-hexane, 2,3-dimethylbutane will have a lower boiling point than n-hexane.
