D. `CaH_(2)`

Answer

To convert N-Ethylphthalimide to Ethylamine, we need to identify the appropriate reagent that will facilitate this transformation. Here’s a step-by-step solution:

### Step 1: Identify the Structures
- **N-Ethylphthalimide** has a structure that includes a phthalimide moiety (a benzene ring with two carbonyl groups adjacent to a nitrogen atom) and an ethyl group attached to the nitrogen.
- **Ethylamine** is a simple amine with the structure CH3CH2NH2.

### Step 2: Understand the Reaction Type
- The conversion from N-Ethylphthalimide to Ethylamine involves the removal of the phthalimide group and the introduction of an amine group (NH2).
- This indicates that we need a reagent that can reduce the phthalimide to release the ethylamine.

### Step 3: Choose the Reagent
- The reagent that is commonly used for the reduction of phthalimides to primary amines is **Hydrazine (NH2NH2)**.
- Hydrazine can effectively reduce the N-ethylphthalimide to ethylamine by breaking the carbonyl bonds and converting the nitrogen in the phthalimide to an amine.

### Step 4: Reaction Mechanism
- When N-Ethylphthalimide is treated with hydrazine, it undergoes a reduction process where the carbonyl groups are reduced and the nitrogen is converted to an amine.
- The side product formed during this reaction is **Thalhydrazide**, which is an intermediate formed before the complete reduction to ethylamine.

### Final Answer
The reagent required for the conversion of N-Ethylphthalimide to Ethylamine is **Hydrazine (NH2NH2)**.
