Which of the following compounds has the largest dipole moment?(i) CH3OH(ii) CH4(iii) CF4(iv) CO2(v) CH3F

Answer»

CH4 and CF4 have tetrahedral structure and are symmetrical, hence their dipole moment is zero, CO2 is linear and hence its dipole moment is also zero of the remaining CH3OH and CH3F, since F is more electronegative than O, CH3F will have high dipole moment.
