A chromatogram was obtained from a gas chromatograph during the separation of a series of alkanes.  The stationary phase was nonpolar.  Would pentane (5-carbons) or dodecane (12-carbons) elute last? Group of answer choices Dodecane, because it will interact more with the stationary phase. Dodecane, because it has a higher boiling point. Pentane, because it will interact more with the stationary phase. Pentane, because it has a lower boiling point.
