MCQ
On heating with conc. ${H_2}S{O_4},$ sucrose gives
  • A
    $CO$ and $C{O_2}$
  • B
    $CO$ and $S{O_2}$
  • C
    $CO,\,\,C{O_2}$ and $S{O_2}$
  • ✓
    None of these
✓

Answer

Correct option: D.
None of these
d
In the presence of concentrated sulfuric acid, sucrose is dehydrated to produce carbon and water. The heat of the reaction vaporizes the water causing the column of carbon to form.Reaction :$C _{12} H _{22} O _{11}+\text { conc. } H _2 SO _4 \rightarrow 12 C +11 H _2 O$
