Question

Assertion (A) $HCl , SO _{2}$ are the examples of polar molecular solids.
Reason (R) These are good conductors of electricity.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
• D. $R$ is correct; $A$ is incorrect.

Answer 1

Answer: (C)

Although $HCl$ and $SO _{2}$ are polar molecular solids but they have neither free electrons nor free ions. Due to the absence of free electrons or ions these are non-conductors of electricity.
