MCQ
Which of the compound does not dissolve in concentrated $\mathrm{H}_2 \mathrm{SO}_4\ ?$
- ✓Hexane
- BBenzene
- CEthylene
- DAniline
✓
Answer
Correct option: A.
Hexane
Hexane does not dissolve in concentrated $\mathrm{H}_2 \mathrm{SO}_4$.
Hexane is nonpolar hydrocarbon. Polar compound such as benzene, ethylene and aniline dissolve in concentrated $\mathrm{H}_2 \mathrm{SO}_4$ as they donate their $\pi$ electrons to $H^+$ ions of concentrated $\mathrm{H}_2 \mathrm{SO}_4$.
