Question

Assertion :$S{O}_2$ gas is easily liquefied while $H_2$ is not. Reason: $S{O}_2$ has low critical temperature while $H_2$ has high critical temperature.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

As $H_2$ is a non-polar compound and have weak van der Waals forces so it does not easily liquefy while $S{O}_2$ is a polar molecule and strong polar forces so it can be easily liquefied.

Thus, Assertion is correct but Reason is incorrect

Hence, the correct option is $\text{C}$
