Given, van der Waal's constant for NH _ 3 , H _ 2 , O _ 2 and CO _...

Given, van der Waal's constant for NH3,H2,O2{NH}_{3}, {H}_{2}, {O}_{2} and CO2{CO}_{2} are respectively 4.17,0.244,1.36and3.594 . 17, 0 . 244, 1 . 36and3 . 59. Which one of the following gases is most easily liquefied?

Options

  1. AO2{O}_{2}
  2. BH2{H}_{2}
  3. CNH3{NH}_{3}
  4. DCO2C{O}_{2}

Correct answer

C. NH3{NH}_{3}

Step-by-step solution

The gas having higher critical temperature gets liquefied easily.

Critical temperature∝∝van der Waal's constant \left(a\right).</p><p>Maximum"a". </p><p>Maximum "a"⇒easiestliquefactioneasiest liquefaction= {NH}_{3}$ .
