Answer: Option (B) is the correct answer.
Explanation:
A molecular compound is defined as the compound in which combining atoms are chemically combined together by sharing of electrons.
This means a covalent bond will be present between the atoms of a molecular compound.
And, a covalent bond is always formed by non-metals.
Therefore, [tex]CS_{2}[/tex], [tex]N_{2}O_{4}[/tex] and [tex]PCl_{3}[/tex] are all molecular compounds as all of them have a covalent bond.
But in [tex]BaI_{2}[/tex], a chemical bond is formed between a metal and a non-metal. Hence, it is not a molecular compound.
Thus, we can conclude that out of the given options [tex]BaI_{2}[/tex] does not represent a molecular compound.
