Which of the following does not represent a molecular compound?
a. cs2

b. bai2

c. n2o4

d. pcl3

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, , and are all molecular compounds as all of them have a covalent bond.

But in , 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 does not represent a molecular compound.
