D. butanoic acid

Answer

To solve the question regarding the reaction of propene with carbon monoxide and hydrogen in the presence of a cobalt carbonyl catalyst at high temperature and pressure, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are propene (C3H6), carbon monoxide (CO), and hydrogen (H2).

2. **Understand the Reaction Conditions**:
- The reaction takes place in the presence of a cobalt carbonyl catalyst under high temperature and pressure. This indicates that the reaction is likely a hydroformylation reaction.

3. **Define Hydroformylation**:
- Hydroformylation is a chemical reaction that involves the addition of a formyl group (CHO) and a hydrogen atom to an alkene. This process converts alkenes into aldehydes.

4. **Analyze the Structure of Propene**:
- Propene has the structure CH2=CH-CH3. It is a three-carbon alkene with a double bond between the first and second carbon atoms.

5. **Reaction Mechanism**:
- In the hydroformylation reaction, the double bond of propene will react with carbon monoxide and hydrogen. The hydrogen adds to one of the carbon atoms of the double bond, while the formyl group (CHO) adds to the other carbon atom.

6. **Determine the Product**:
- After the reaction, we will have a four-carbon chain with an aldehyde functional group. The structure of the product will be CH3-CH2-CH2-CHO.

7. **Naming the Product**:
- The product has four carbon atoms and contains an aldehyde group. Therefore, the IUPAC name of the product is butanal (commonly referred to as butyraldehyde).

8. **Final Answer**:
- The product formed from the reaction of propene with carbon monoxide and hydrogen in the presence of cobalt carbonyl catalyst at high temperature and pressure is butanal.
