Write the chemical equations when: Sugar reacts with conc. `H_2SO_4`.

Text Solution

Verified by Experts

Concentrated `H_2 SO_4` is a strong dehydrating agent. It dehydrates oxalic acid to a mixture of CO and `CO_2`, formic acid to CO and sugar to sugar charcoal.
`underset("Sugar")(C_(12) H_(22) O_(11)) underset(Delta)overset("Conc". H_2 SO_4)to underset("Sugar charcoal")(12 C) + 11 H_2 O`
