Quizplus · Accepted Answer

The C-N-O bonds in the given structure are all in the same plane and are arranged in a trigonal planar geometry around the nitrogen atom. In a trigonal planar geometry, the bond angle between any two bonds is expected to be approximately 120°. Therefore, the bond angle for the C-N-O bonds in the given molecule would be expected to be approximately 120°.
