Question

Fill in the blanks with suitable words:

Sugar charcoal can be obtained by……..of sugar with concentrated sulphuric acid

Answer 1

Destructive distillation:

• Destructive distillation can be defined as the chemical process through which unprocessed materials are subjected to decomposition by heating them and thereby producing 'cracks' in the relatively large molecules.
• The decomposition of a complex substance, such as wood or coal, by heating it in the absence of air and collecting volatile products.
• Sugar charcoal is prepared by the destructive distillation of sugar.it can also be obtained by dehydrating sugar with concentrated sulphuric acid.

$\underset{\mathrm{Sugar}}{{\mathrm{C}}_{12}^{}{\mathrm{H}}_{22}^{}{\mathrm{O}}_{11}^{}}\underset{}{\stackrel{\mathrm{conc}.{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }\underset{\mathrm{Carbon}}{12\mathrm{C}}+\underset{\mathrm{Water}}{11{\mathrm{H}}_2^{}\mathrm{O}}}$

Therefore, Sugar charcoal can be obtained by destructive distillation of sugar with concentrated sulphuric acid.
