D. Picrates

Answer

To solve the question regarding the compounds formed when noble gases are entrapped in the cavities of crystal lattices of certain organic and inorganic compounds, we can follow these steps:

### Step 1: Understand the Concept of Crystal Lattices
A crystal lattice is a three-dimensional arrangement of atoms or molecules in a crystalline material. In this structure, there are voids or empty spaces between the lattice points where other molecules can be accommodated.

**Hint:** Think about how atoms are arranged in a solid and the spaces that might exist between them.

### Step 2: Identify the Voids in the Lattice
In the crystal lattice, the empty spaces between the arranged atoms or molecules are referred to as voids. These voids can trap other molecules, including gases.

**Hint:** Consider what happens in a solid structure when there are gaps or spaces.

### Step 3: Recognize the Role of Noble Gases
Noble gases, which include Helium, Neon, Argon, Krypton, and Xenon, are known for their lack of reactivity. They can exist in a gaseous state and can be trapped within the voids of a crystal lattice without reacting with the host material.

**Hint:** Remember that noble gases are chemically inert and do not readily form compounds under normal conditions.

### Step 4: Define the Type of Compounds Formed
When noble gases are trapped in the voids of a crystal lattice, the resulting compounds are specifically known as clathrate compounds. Clathrates are characterized by their ability to encapsulate gas molecules within a structured host lattice.

**Hint:** Think about the term "clathrate" and how it relates to the concept of trapping or enclosing something.

### Final Answer
The compounds formed when noble gases get entrapped in the cavities of crystal lattices of certain organic and inorganic compounds are known as **clathrate compounds**.
