A binary molecular compound is composed of two different elements chemically bonded together in a specific ratio to form molecules. In these compounds, the atoms are held together by covalent bonds, where electrons are shared between the atoms.

On the other hand, AgI is an ionic compound, not a molecular compound. In AgI, silver (Ag) and iodine (I) are present as ions, held together by electrostatic forces of attraction between positively charged silver ions (Ag+) and negatively charged iodide ions (I-). The electrostatic attraction between oppositely charged ions forms a crystal lattice structure, rather than discrete molecules.

Therefore, AgI is classified as an ionic compound, not a binary molecular compound.
