MOLECULAR POLARITYFIELD NOTE 130 / 175
Is Isopropanol (C3H8O) polar or nonpolar?
Isopropanol (C3H8O) is polar because the middle-carbon –OH group creates polar C–O and O–H bonds.

Why C3H8O is polar
In 2-propanol, oxygen is bonded to the central carbon and to hydrogen. Its two lone pairs and the electronegativity difference across C–O and O–H produce an uneven charge distribution that the two methyl groups do not cancel.
What to notice
Isopropanol and 1-propanol share the formula C3H8O but connect the –OH group at different positions. A formula alone cannot distinguish these two 3D structures.
