MCQ
Which of the following compounds is insoluble even in hot concentrated ${H_2}S{O_4}$
  • A
    Ethylene
  • B
    Benzene
  • ✓
    Hexane
  • D
    Aniline
✓

Answer

Correct option: C.
Hexane
c
Hexane is an alkane which is also called as paraffin or less reactive. Thus they are not soluble in concentrated $H _2 SO _4$.

Also, hexane is non-polar and concentrated $H _2 SO _4$ is polar, thus hexane is not soluble in $H _2 SO _4$.
