the term Y is

Options

C. acetaldehyde
D. dimethyl amine

Explanation

To solve the problem, we will analyze the reaction step by step.

### Step 1: Identify the Reactants
The reactants given in the question are:
- Acetonitrile (CH₃CN)
- Hydrogen gas (H₂)
- Hydrochloric acid (HCl)
- Ether as a solvent

### Step 2: Reaction of Acetonitrile with Hydrogen
In the presence of HCl and ether, acetonitrile (CH₃CN) reacts with hydrogen gas (H₂). The reaction involves the reduction of the nitrile group (–C≡N) to an imine (–C=N–) or amine (–C–NH₂).

The reaction can be represented as:
\[ \text{CH}_3\text{CN} + 2 \text{H}_2 \xrightarrow{\text{HCl, Ether}} \text{X} \]

### Step 3: Formation of the Imine or Amine
When CH₃CN reacts with hydrogen in the presence of HCl, it forms an intermediate product, which is an imine (or possibly an amine). The structure of the product X can be represented as:
\[ \text{CH}_3\text{C}(\text{H})=\text{NH} \]

### Step 4: Boiling with Water
Next, we take the product X and boil it with water (H₂O). The boiling with water typically leads to hydrolysis of the imine or amine, replacing the nitrogen atom with an oxygen atom.

The reaction can be represented as:
\[ \text{X} + \text{H}_2\text{O} \rightarrow \text{Y} \]

### Step 5: Identify Product Y
When the imine (or amine) undergoes hydrolysis, it forms an aldehyde. In this case, the product Y will be acetaldehyde (CH₃CHO).

### Conclusion
Thus, the term Y in the given reaction is acetaldehyde (CH₃CHO).

### Final Answer
The term Y is acetaldehyde.
