Explain why phenol has smaller dipolemoment than methanol?
The lone pair on oxygen atom is used for delocalization in the phenol ring due to which there is a double bond character between C-OH bond and there is positive charge on the oxygen atom as well due to which phenol is less polar and thus has less dipole moment.

In methanol, CH3-OHcarbon has a partial positive charge and oxygen has a partial negative charge and the bond between C and OH is single due to which methanol is more polar and has more dipole moment.
