Which gas among the following is the easiest to liquify?

Options

  1. ASO ₂
  2. BN ₂
  3. CNH ₃
  4. DCO ₂

Correct answer

A. SO ₂

Step-by-step solution

SO ₂ is a polar molecule with strong intermolecular forces of attraction and high value of van der Waals' constant ' a ' Also SO ₂ is a temporary gas that has high critical temperature. So, it can be liquified easily.
