The shape of NH-2 is :
Correct answer: B. Angular
- A. Linear
- B. Angular
- C. Pyramidal
- D. Tetrahedral
Explanation
NH2- ion has a total of 8 valence electrons. 2 pairs are bonding and 2 are non-bonding and stay confined to the Nitrogen atom. The overall shape is bent (aka angular) with 104.5 degree bond angles due to strong lone pair-bonding pair repulsion that pushes the 2 bonding pairs closer together.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
