उत्तर
H2SP4 has a great affinity for water. It readily removes elements of water from other compounds, i.e., it acts as a dehydrating agent.
\[\ce{\underset{(Glucose)}{C6H12O6} ->[Conc. H2SO4] 6C + 6H2O}\]
\[\ce{\underset{(Cane Sugar)}{C12H22O11} ->[Conc. H2SO4] \underset{Sugar Charcoal}{12C_{(s)} + 11H2O}}\]
