Question

Which of the compound does not dissolve in concentrated $H_{2}S{O}_4$?

• A. Hexane
• B. Benzene
• C. Ethylene
• D. Aniline

Answer 1

Answer: (A)

Hexane

$Hexane$ does not dissolve in concentrated $H_{2}S{O}_4$. $Hexane$ is nonpolar hydrocarbon. Polar compound such as $benzene$, $ethylene$ and $aniline$ dissolve in concentrated $H_{2}S{O}_4$ as they donate their $\pi$ electrons to $H^{+}$ ions of concentrated $H_{2}S{O}_4$.

Option A is correct.
