Final answer:
The molecular structure of the stable form of FNO₂ with nitrogen as the central atom is bent (V-shaped), due to the sp² hybridization of nitrogen and the repulsion between the lone pair and bonding pairs of electrons.
Step-by-step explanation:
The molecular structure of the stable form of FNO₂, with nitrogen as the central atom, is bent (V-shaped). Nitrogen is sp² hybridized in this molecule, leading to a planar structure with a lone pair of electrons on the nitrogen.
This results in a bent geometry with the ONO bond angle slightly less than 120° due to the repulsion between the lone pair and the bonding pairs of electrons.
