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

💡 Solution & Explanation

I notice the options (A, B, D) aren't provided in your question, so I'll explain the general principle for identifying water-insoluble gases: **Key Concept:** Gases dissolve in water based on: 1. **Polarity** — polar gases dissolve well; nonpolar gases don't 2. **Hydrogen bonding ability** — gases that form H-bonds with $H_2O$ are soluble 3. **Chemical reactivity** — gases that react with water dissolve **Common Water-Soluble Gases:** - $HCl$, $HBr$, $NH_3$, $SO_2$, $CO_2$ (all form H-bonds or react) **Common Water-Insoluble Gases:** - $O_2$, $N_2$, $H_2$, $CH_4$, $C_2H_6$ (nonpolar, no H-bonding) **Without seeing option C specifically**, the answer is likely a **nonpolar gas** like $N_2$, $O_2$, or a hydrocarbon, which lacks both polarity and the ability to form hydrogen bonds with water molecules. --- *Please provide the options so I can confirm why C is correct and explain why the other options are wrong.*
