Question

Match the following allotropes of carbon with their respective applications.

• A. Nanotechnology
• B. Gas mask
• C. Shoe polish

Answer 1

The correct option is

• Fullerene (${\text{C}}_{60}$) is an allotrope of carbon which has a structure that is similar to a soccer ball. It is used in electronics, t.v. picture tubes and also in nanotechnology and nanomedicine.
• Activated charcoal has high adsorbing ability. It is used in gas masks as the fine holes in the charcoal prevents the large toxic gases like ammonia from passing through it.
• Lampblack (soot) is soft fine powder obtained by burning carbon rich substances. It is used in shoe polish and kajal.
