Question:

$\text{The correct statement regarding the van der Waal constant of } \text{N}_2 \text{ \& } \text{NH}_3 \text{ is -}$

Options:

1. $a_{\text{NH}_3} > a_{\text{N}_2}, b_{\text{NH}_3} < b_{\text{N}_2}$
2. $a_{\text{NH}_3} < a_{\text{N}_2}, b_{\text{NH}_3} < b_{\text{N}_2}$
3. $a_{\text{NH}_3} > a_{\text{N}_2}, b_{\text{NH}_3} > b_{\text{N}_2}$
4. $a_{\text{NH}_3} < a_{\text{N}_2}, b_{\text{NH}_3} > b_{\text{N}_2}$

Solution:

$\text{Hint- a is measure of intermolecular strength and b depends upon molecular weight}$ $\text{EXPLANATION}$ $\text{Higher the polarity, easier to liquify.}$ $\text{The ease of liquification of a gas depends on their intermolecular force of attraction. Hence, higher the value of 'a', greater the intermolecular force of attraction, easier to liquify. In the present case, } \text{NH}_3 \text{ has highest 'a', can most easily be liquefied. Molecular weight of } \text{NH}_3 \text{ is higher than } \text{N}_2 \text{, so } b_{\text{NH}_3} > b_{\text{N}_2}$
