• A. Diamond:- Used for cutting and drilling rocks Fullerene:- Used for making pencil leads
• B. Lamp Black:- Used to make shoe polishes Fullerene:- Used for making superconductors
• C. Diamond:- Used for cutting and drilling rocks Bone charcoal:- To decolourise cane sugar
• D. Bone charcoal:- To decolourise cane sugar Fullerene:- Used for making pencil leads

Answer 1

Answer: (B), (C)

The correct options are
B

Lamp Black:- Used to make shoe polishes

Fullerene:- Used for making superconductors

C

Diamond:- Used for cutting and drilling rocks

Bone charcoal:- To decolourise cane sugar

Uses of allotropes of carbon:-

(1) Lamp Black or Soot:- It is an amorphous form of carbon and is used to make shoe polishes.

(2) Fullerene:- It is a crystalline form of carbon and is used as insulators and to make superconductors (Substance having very low resistance).

(3) Bone charcoal:- It is an amorphous form of carbon and is used to decolourise cane sugar

(4) Diamond:- It is a crystalline form of carbon and is used for cutting and drilling rocks because it is the most hardest naturally occurring substance.
