Which of the following compounds would have the highest boiling point?

$2-$methyl but$$ne$,C_5{H}_{12}$

pentane due to its higher molar mass

pentane due to its large contact area

$2-$methyl butane tiue to its higher molar mass

$2-$methyl butane due to its large contact area

Both compounds would have the same boiling point due to having the same chemical formula.
