Question

What type of bonding is present in clathrate compounds?

• A. Ionic
• B. Covalent
• C. Coordinate
• D. No bond formation

Hint:

Clathrates are like a "bird in a cage"—the bird isn't glued to the bars; it's just trapped by the structure!

Answer 1

The Correct Option is D

Step 1: Concept Clathrates are inclusion complexes where "guest" molecules are physically trapped inside the cavities of a "host" lattice.

Step 2: Meaning The trapping is purely based on size and structural fit rather than chemical reactivity.

Step 3: Analysis There is no exchange or sharing of electrons between the host (e.g., quinol or water) and the guest (e.g., Argon or Methane). The components are held together by weak van der Waals forces or simply physical cage entrapment.

Step 4: Conclusion Therefore, in a formal chemical sense, there is no bond formation (ionic, covalent, or coordinate). Final Answer: (D)
