Match List - I with List - II Choose the correct answer from the options given below :
| List - I | List - II |
|---|---|
| A. Coke | I. Carbon atoms are hybridised. |
| B. Diamond | II. Used as a dry lubricant |
| C. Fullerene | III. Used as a reducing agent |
| D. Graphite | IV. Cage like molecules |
- Option A:
A-IV, B-I, C-II,D-III
- Option B:Correct
A-III, B-I, C-IV,D-II
- Option C:
A-III, B-IV, C-I,D-II
- Option D:
A-II, B-IV, C-I,D-III
Answer: B
Step-by-step solution
l• Coke is largely used as a reducing agent in metallurgy.
• In diamond, each carbon atom undergoes sp3 hybridisation and linked to four other carbon
atoms by using hybridised orbitals in tetrahedral fashion.
• Buckminsterfullerene contains six membered and five membered rings and hence is a
cage like molecule.
• Graphite is very soft and slippery. Hence, it is used as a dry lubricant in machines
running at high temperature.
