What is the CNN bond angle in the compound shown below?

Question

Quizplus · Accepted Answer

The CNN bond angle in the compound shown is approximately tetrahedral, which means the bond angle should be close to 109.5°. However, there are two lone pairs of electrons on the nitrogen atom, which repel more strongly than bonded electrons. As a result, the angle between the C-N bonds is decreased to around 120°. Therefore, the best choice is D, with a bond angle of approximately 120°.
