(a)
Interpretation:
The bond angle of each atom of carbon, nitrogen and oxygen in given structural formula should be predicted.
Concept Introduction:
VSEPR model is useful to predict bond angles occurred between atoms of a molecule. The bond angle of atom is a point where two atoms are joined together. The valence-shell electron-pair repulsion model is full form of VSEPR model.
(b)
Interpretation:
The bond angle of each atom of carbon, nitrogen and oxygen in given structural formula should be predicted.
