Which from following gases is least soluble in water under same conditions of temperature and pressure ?

Options

  1. AHCl
  2. BCO ₂
  3. CNH ₃
  4. DO ₂

Correct answer

D. O ₂

Step-by-step solution

Water is a polar solvent. Gases that are polar, can form hydrogen bonds, or react with water are highly soluble in it. HCl and NH ₃ are highly soluble due to ionization and hydrogen bonding, respectively. CO ₂ is moderately soluble as it reacts with water to form carbonic acid. O ₂ is a non-polar gas and interacts with water only through weak dipole-induced dipole forces, making it the least soluble among the given gases. Answer: O ₂
