Current Question (ID: 8231)

Question:

$\text{The gas among the following that can be most steadily liquefied is - }$

Options:

1. $\text{NH}_3$
2. $\text{Cl}_2$
3. $\text{SO}_2$
4. $\text{CO}_2$

Solution:

$\text{Hint: Gas having a high force of attraction liquify easily}$ $\text{SO}_2 \text{ has a higher value of van der Waals' forces of attraction and thus, is more easily liquefied.}$ $\text{value of 'a' for}$ $\text{CO}_2 = 3.6$ $\text{SO}_2 = 6.8$ $\text{Cl}_2 = 6.6$ $\text{NH}_3 = 4.2$ $\text{SO}_2 \text{ has higher value of "a" hence it has maximum forces of attraction, thus, it will liquify easily.}$
