Which from following gases is least soluble in water at same temperature and pressure ?
Options
- ANH ₃
- BCO ₂
- CHCl
- DN ₂
Correct answer
D. N ₂
Step-by-step solution
Solubility of a gas in water depends on its ability to interact with water molecules. Water is a polar solvent. NH ₃ is highly soluble in water due to its ability to form intermolecular hydrogen bonds with water. HCl is a polar molecule that ionizes completely in water, making it highly soluble. CO ₂ is moderately soluble because it reacts with water to form carbonic acid ( H ₂ CO ₃ ). N ₂ is a non-polar diatomic gas that neither reacts with water nor forms hydrogen bonds. Therefore, it has the weakest interaction
