प्रश्न

Alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses. Explain this fact.

रासायनिक समीकरणे/रचना
स्पष्ट करा

उत्तर

Alcohols are more soluble in water compared to hydrocarbons with equivalent molecular weight because alcohol molecules form hydrogen bonds with water and can also break the existing hydrogen bonds between water molecules, while hydrocarbons are unable to do this.
