Sorry I can't put the vertical lines in for the bonds. Isopropyl alcohol is a little bit negative around the OH, but the difference in electronegativity between C and O is much less than the difference between H and O in water. The difference between H and O in the alcohol is diminished by the electrons contributed to the O by the C. In water O pulls the electrons away from H with much greater force making a large negative electron cloud around the O and a relatively positive area around the Hs.
