Which of the following statements about the conformations of acyclic alkanes is true?
A)A staggered conformation with two larger groups 180° from each other is called gauche.
B)Staggered conformations are at energy maxima and eclipsed conformations are energy minima.
C)A staggered conformation with two larger groups 60° from each other is called anti.
D)Gauche conformations are generally higher in energy than anti conformations.

Question

Quizplus · Accepted Answer

Gauche conformations involve two larger groups being closer together (typically 60° apart), which increases steric hindrance and thus energy, compared to anti conformations where the groups are 180° apart, minimizing steric hindrance and energy.
