Which of the following is true of hydrogen bonding in amines?
A) Amines do not form hydrogen bonds because there is no difference in the electronegativities of nitrogen and hydrogen.
B) The N-H N hydrogen bond is stronger than the O-H O hydrogen bond.
C) The N-H N hydrogen bond is the same strength as that of O-H O hydrogen bond.
D) The N-H N hydrogen bond is weaker than the O-H O hydrogen bond.

Question

Which of the following is true of hydrogen bonding in amines?
A) Amines do not form hydrogen bonds because there is no difference in the electronegativities of nitrogen and hydrogen.
B) The N-H> N hydrogen bond is stronger than the O-H> O hydrogen bond.
C) The N-H> N hydrogen bond is the same strength as that of O-H> O hydrogen bond.
D) The N-H> N hydrogen bond is weaker than the O-H> O hydrogen bond.

Quizplus · Accepted Answer

The N-H> N hydrogen bond is weaker than the O-H> O hydrogen bond because oxygen is more electronegative than nitrogen, leading to a stronger partial charge difference in the O-H bond compared to the N-H bond. This results in stronger hydrogen bonding in compounds with O-H bonds.
