Answer

To solve the question regarding the reaction of 1-butyne with KMnO4 under heating conditions, we can follow these steps:

### Step 1: Identify the structure of 1-butyne
1-butyne is an alkyne with the formula C4H6. Its structure can be represented as:
\[ \text{CH}_3\text{CH}_2\text{C} \equiv \text{CH} \]

### Step 2: Understand the reaction conditions
The reaction involves the use of alkaline potassium permanganate (KMnO4) and heat. KMnO4 is a strong oxidizing agent, and under these conditions, it will oxidize the alkyne.

### Step 3: Determine the products of the reaction
When 1-butyne is oxidized by alkaline KMnO4, it undergoes oxidative cleavage. This reaction typically results in the formation of carboxylic acids and other products. Specifically, 1-butyne will be oxidized to form:
- Acetaldehyde (ethanal, CH3CHO)
- Carbon dioxide (CO2)

### Step 4: Identify X and Y
From the oxidation of 1-butyne:
- **X** is acetaldehyde (CH3CHO)
- **Y** is carbon dioxide (CO2)

### Final Answer
Thus, the products of the reaction are:
- **X = Acetaldehyde (CH3CHO)**
- **Y = Carbon Dioxide (CO2)**
