Is the O-H bond in methanol polar or nonpolar?
It is polar because the oxygen atom has a greater electronegativity than the hydrogen atom.
The O-H bond in methanol is polar in the same way the O-H bonds in water are polar. The oxygen atom is more electronegative than the hydrogen atom, so the shared electrons are held more closely by the oxygen atom. This results in the oxygen atom having a partial negative charge and the hydrogen atom having a partial positive charge.

As a result of this, a polarity develops in the
