Answer :
N2O4 is the only option from the list that represents a molecular compound, since compounds must contain at least two different atoms, although these can be from different groups.
Answer: Option (3) is the correct answer.
Explanation:
A molecular compound is a compound in which atoms used to share electrons and thus results in the formation of covalent bonds.
For example, [tex]N_{2}O_{4}[/tex] is a covalent compound and hence, it is a molecular compound.
Whereas LiOH and NaI are ionic compounds as their atoms has transferred electrons.
Therefore, we can conclude that out of the given options, [tex]N_{2}O_{4}[/tex] is the formula which represents a molecular compound.
