Explanation:

- Dinitrogen trioxide is a molecular compound formed by the covalent bonding of nitrogen and oxygen atoms.

- It does not consist of ions and hence, is not ionic in nature.

- The electronegativity difference between nitrogen (3.0) and oxygen (3.5) is not significant enough to result in the complete transfer of electrons, leading to the formation of ions.

- Instead, the atoms share electrons to achieve a stable electronic configuration.

- The covalent bonds in dinitrogen trioxide involve the sharing of electrons between nitrogen and oxygen atoms, resulting in a neutral molecule.
