Chemical Bonding And Molecular Structure

Given : that \({\mu _{obs}} = \sum {{\mu _i}\,{x_i}}\) where \({\mu _i}\) is the dipole moment of stable conformer and \({x_i}\) is the mole fraction of that conformer.

(A) Write stable conformer for Z-CH\(_2\)-CH\(_2\)-Z in Newman's projection.

If \({\mu _{solution}}\) = 1.0 D and mole fraction of anti-form = 0.82, find \({\mu _{Gauche}}\).

(B) Write most stable meso conformer of

If (i) Y = CH\(_3\) about C\(_2\) - C\(_3\) rotation and (ii) Y = OH about C\(_1\) - C\(_2\) rotation.
