what is the closest bond angle around the central atom? 109.5° 90° 180° 120°
what is the closest bond angle around the central atom? 109.5° 90° 180° 120°
Answer
Answer:
120°
Explanation:
Step1: Determine electron - pair geometry
The central N atom in $NO_3^-$ has 3 bonding pairs and 0 lone pairs. Using VSEPR theory, the electron - pair geometry is trigonal planar.
Step2: Identify bond angle
For a trigonal - planar electron - pair geometry, the bond angle is 120°.
