Single Choice

Which of the following statements is not true about conformational isomerism ?

AThese can be represented by Newman and Sawhorse projections.
BThe number of conformational isomers is infinite.
CThe eclipsed form is most stable.
Correct Answer
DConformational isomerism is also found in the cyclic compound.

Solution

Conformational isomers can be represented by newman and sawhorse projections. No. of conformational isomers of a compound is infinite. Generally, staggered form is most stable. Conformational isomerism is also found in cyclic compounds. Hence, Option "C" is the correct answer.

$$ \mu $$ 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 .
