Which of the following amines can be resolved into enantiomers?
A) trimethylamine
B) 3-pentanamine
C) 2-pentanamine
D) dimethylammonium chloride
E) 4-(dimethylamino) pyridine

Question

Quizplus · Accepted Answer

Amines with a chiral center can exist as enantiomers, meaning 2-pentanamine with a chiral center can be resolved into enantiomers. Trimethylamine does not have a chiral center, so it cannot exist as enantiomers. Similarly, 3-pentanamine does not have a chiral center, so it cannot exist as enantiomers. Dimethylammonium chloride is not an amine with a chiral center, as it does not have a nitrogen atom bonded to three different substituents, so it cannot exist as enantiomers. 4-(dimethylamino) pyridine is not an amine with a chiral center, as the nitrogen atom is bonded to two identical methyl groups, so it cannot exist as enantiomers.
