- A \(\mathrm{C}_{70}\) as main product and \(\mathrm{C}_{80}\) in small quantities
- B \(\mathrm{C}_{60}\) as main product and \(\mathrm{C}_{70}\) in small quantities
- C \(\mathrm{C}_{50}\) as main product and \(\mathrm{C}_{60}\) in small quantities
- D equal amounts of \(\mathrm{C}_{60}\) and \(\mathrm{C}_{70}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{C}_{60}\) as main product and \(\mathrm{C}_{70}\) in small quantities
Step-by-step Solution
Detailed explanation
Fullerenes are molecules with 60 carbon atom of which most common is \(\mathrm{C}_{60}\) while others with \(\mathrm{C}_{70}, \mathrm{C}_{76}, \mathrm{C}_{80}\) atoms. Fullerenes can be made in a carbon arc, where two graphite rods are placed with a small gap between them in an…
