Vedclass · Answer

(B) The potential energy of a conformer is determined by the steric strain and torsional strain present in the molecule.In the given Newman projections,we analyze the interactions between the substituents ($Me$ and $Et$ groups) on the two carbon atoms.$III$: The $Me$ and $Et$ groups are gauche to each other,creating significant steric repulsion.$I$ and $II$: In both cases,the $Me$ and $Et$ groups are anti to each other,which is more stable than the gauche interaction. Since the structures are equivalent,their potential energies are equal $(I = II)$.$IV$: The $Me$ and $Et$ groups are anti to each other,but the overall arrangement is the most stable among the given options due to minimal steric hindrance.Thus,the decreasing order of potential energy is $III > I = II > IV$.

Arrange the given compounds in decreasing order of their potential energy:
