`mu` observed `= Sigma mu_(i)X_(i)`
where `mu_(i)` is the dipole moment of the stable conformer and `X_(i)` is the mole fraction of that conformer.
(a) Write the stable conformer for `(Z--CH_(2)--CH--Z)` in Newman's projection. If `mu_(solution) = 1.0` D and mole fraction of the antiform `=0.82`, find the `mu` gauche form.
(b) Write the most stable meso conformer of `underset(CHDY)(underset(|)(CHDY))`
If (i) `Y = CH_(3)` about `C_(2)-C_(3)` rotation and (ii) `Y = OH`, about `C_(1)-C_(2)` rotation.
