What is the relationship between the molecules in the following pairs ?

A$$ Enantiomers $$
B$$ Distereomers $$
C$$ Identical $$
Correct Answer
D$$ Structural \quad isomers $$

Solution

In fischer most oxidised end remains always on top so rotation of $$ II^{nd} $$ str by $$ 180^0 $$ . it is clear that $$ I $$ & $$ II $$ are identical .

$$ \mu $$ observed = $$ \sum \mu_iX_i $$ where $$ \mu_i $$ is the dipole moment of the stable conformer and $$ X_i $$ is the mole fraction of that conformer. 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 .
