Which of the following gases will be least soluble in water?a)Hydrogen chlorideb)Sulphur dioxidec)Ammoniad)NitrogenCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

Option (d) becoz---->

N2 in water is that they just occupy the intermolecular spaces and stays there by interaction with its surrounding molecules by weak van der Waals forces.....So it is least soluble while other gases form hydrogen bonds with water

Answer

Just  remember one thing like dissolves like. hydrogen chloride Sulphur dioxide ammonia all are polar molecules while nitrogen is nonpolar as we all know water is an ionic compound so nitrogen will be least stable.

Answer

Elementary gases are least soluble than compoundary gases

Answer

The correct answer is Option D.
The reason for poor solubility of N2 in water is that they just occupy the intermolecular spaces and stay there by interaction with its surrounding molecules by weak van der Waals forces.So it is least soluble while other gases form hydrogen bonds with water.

Answer

Explanation:

Factors affecting gas solubility in water:
- Temperature: Generally, gas solubility decreases with increasing temperature.
- Pressure: Higher pressure typically increases gas solubility.
- Chemical nature of the gas and solvent: Different gases have different solubilities in water based on their chemical properties.

Least soluble gas in water:
- Nitrogen (N2): Nitrogen is the least soluble gas in water among the options given. Nitrogen is relatively nonpolar and does not readily form hydrogen bonds with water molecules, making it less soluble compared to the other gases listed.
- Hydrogen chloride (HCl): Hydrogen chloride is a polar molecule and can readily form hydrogen bonds with water, increasing its solubility.
- Sulphur dioxide (SO2): Sulphur dioxide is also a polar molecule and can form hydrogen bonds with water, making it more soluble than nitrogen.
- Ammonia (NH3): Ammonia is a polar molecule that can form hydrogen bonds with water molecules, resulting in higher solubility compared to nitrogen.
Therefore, nitrogen will be the least soluble gas in water among the options provided due to its nonpolar nature and inability to form strong interactions with water molecules.
