3 non-polar bonds


There are 3 C-H bonds, 1 C-O bond and 1 O-H bond in methanol, #CH_3OH#. Because the electronegativity (EN) difference between C and H is very small, the C-H bond is considered non-polar. The EN of O is very large, resulting in both the C-O and the O-H bonds being polar.

However, do note that the oxidation state of C is -2. Between C and H, C is more electronegative and will gain a -1 from each C-H bond when calculating its oxidation state.
