yes because in the molecule CH3OH, oxygen has a very high electronegativity (tendency to atract electrons toward its nucleus) and as such, it pulls the electrons of the sigma-bonds with carbon and hydrogen, toward itself and takes on a partial negative charge. The carbon and especially the OH hydrogen have partial loss of electrons in the bond, and thus assume a partial positive charge. In solution, the negative oxygen centers attract the positive hydrogen centers and form what is known as hydrogen bonding, an electrostatic attraction between oxygen (-) and hydrogen (+). The molecule has an unequal distribution of +/- charge on its surface, and thus is deemed polar. Contrast this with methane (CH4) which is non-polar for symmetrical geometric reasons as well as electronagtivity reasons.
