Which has higher boiling points among butan‐2‐ol (1) and 2‐methylpropan‐1‐ol (2)?

1: 2‐butanol; 2: isobutanol

I know that branching decreases the boiling points, but I want to know how position of substituents affects the melting (m.p.) and boiling points (b.p.). Google search only resulted in the b.p. of isobutyl alcohol listed in Wikipedia: 107.9 °C.

    $\begingroup$ 2-butanol should be written instead of 1-methyl propanol as it is an incorrect IUPAC name. $\endgroup$
