WebOct 13, 2024 · The dipole moment of cis-compound is a sum of the dipole moments of C–CH 3 and C– CH 2 CH 3 bonds acting in the same direction. The dipole moment of trans-compound is the resultant of the dipole moments of C–CH 3 and C–CH 2 CH 3 bonds acting in opposite directions. Hence, cis-isomer is more polar than trans-isomer.
