Which gas among the following is the easiest to liquify?
- A \(\mathrm{SO}_2\)
- B \(\mathrm{N}_2\)
- C \(\mathrm{NH}_3\)
- D \(\mathrm{CO}_2\)
Answer & Solution
Correct Answer
(A) \(\mathrm{SO}_2\)
Step-by-step Solution
Detailed explanation
\(\mathrm{SO}_2\) is a polar molecule with strong intermolecular forces of attraction and high value of van der Waals' constant '\(a\)' Also \(\mathrm{SO}_2\) is a temporary gas that has high critical temperature. So, it can be liquified easily.
