# Vanderwaal real gas constants

**Chemistry**Level pending

\[1. \text{NH}_3 \qquad 2. \text{N}_2 \qquad 3. \text{CH}_{2}\text{Cl}_2 \qquad 4. \text{Cl}_2 \qquad 5. \text{CCl}_4\]

Predict which of the above gases have:

(i) the smallest van der Waals "a" constant

(ii) the largest "b" constant.

Concatenate the answer, for an example if gas \(1. \text{NH}_3\) fits part (i) and gas \(4. \text{Cl}_2\) fits the part (ii), then enter the answer as 14. For a and b refer van der waal
