Question

_______________ is the the purest form of amorphous carbon.

Answer 1

Sugar charcoal:

• Sugar charcoal is the purest form of amorphous $\mathrm{Carbon}\left(\mathrm{C}\right)$.
• It is prepared by heating $\mathrm{Glucose}\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$ in the absence of air.
• It can also be prepared by dehydration of glucose in the presence of $\mathrm{Sulphuric}\mathrm{acid}\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$.

Thus, Sugar charcoal is the purest form of amorphous carbon.
