Among the following, van der Waals' constant \(a\) would be maximum for
- A \(\mathrm{H}_2\)
- B \(\mathrm{O}_2\)
- C \(\mathrm{CH}_4\)
- D \(\mathrm{NH}_3\)
Answer & Solution
Correct Answer
(D) \(\mathrm{NH}_3\)
Step-by-step Solution
Detailed explanation
van der Waals' constant (a) depend upon attraction i.e. \[ a \propto \text { attraction } \] There is maximum attraction in \(\mathrm{NH}_3\) because there is \(\mathrm{H}\)-bond and in all other compounds, have van der Waals' force.
