2023 The p-Block Elements (Group 13 and 14)Allotropes of Carbon Easy Question 1 of 2 in Allotropes of Carbon

Match List-I with List-II

Column I

  • A. Coke
  • B. Diamond
  • C. Fullerene
  • D. Graphite

Column II

  • I. Carbon atoms are $sp^3$ hybridised.
  • II. Used as a dry lubricant
  • III. Used as a reducing agent
  • IV. Cage like molecules

Correct answer: A → III, B → I, C → IV, D → II

Solution

Coke is a reducing agent, diamond is sp3, fullerene is cage-like, graphite is a lubricant.

Coke – reducing agent Diamond – $sp^3$ carbons Fullerenes – cage like structure Graphite – used as lubricant
