Which of the following gas in insoluble in water? — Hydrogen Chemistry Question

💡 Solution & Explanation

I need to identify which gas is insoluble in water. However, your question doesn't show the options (A, B, C, D). Let me provide a general approach and common examples: **General Principle:** Gases dissolve in water based on their polarity and ability to form hydrogen bonds or ionic interactions. **Common gas solubility patterns:** | Gas | Solubility | Reason | |-----|-----------|--------| | $CO_2$ | Soluble | Forms $H_2CO_3$ (carbonic acid) | | $SO_2$ | Soluble | Forms $H_2SO_3$ | | $NH_3$ | Very soluble | Forms hydrogen bonds | | $O_2$ | Slightly soluble | Non-polar, low polarity | | $N_2$ | Insoluble | Non-polar, diatomic molecule | | $CH_4$ | Insoluble | Non-polar hydrocarbon | | $H_2$ | Insoluble | Non-polar diatomic molecule | **If option C is the correct answer, it's likely:** - A **non-polar gas** like $N_2$, $O_2$, $H_2$, or $CH_4$ - Lacks polar functional groups - Cannot form hydrogen bonds with water **The key reasoning:** Insoluble gases are **non-polar molecules** that cannot interact favorably with the polar $H_2O$ solvent ("like dissolves like" principle). *Please share the options to confirm which specific gas is option C.*
