Question

Predict the order of boiling points, low to high, for these three amines. I.(CH₃)₃N II.CH₃CH₂NHCH₃ III.CH₃CH₂CH₂NH₂ A) I < II < III B) III < II < I C) I < III < II D) II < III < I E) II < I < III

Quizplus · Accepted Answer

The boiling point order is determined by the ability to form hydrogen bonds and molecular weight. Primary amines like III can form more hydrogen bonds than secondary amines like II, and tertiary amines like I cannot form hydrogen bonds with themselves. Therefore, III has the highest boiling point, followed by II, and I has the lowest.
