C. Propanone & propanal
D. Propan-2-ol and ethanal

Answer

To determine the products formed from the ozonolysis of 2-methylpent-2-ene, we can follow these steps:

### Step 1: Identify the structure of 2-methylpent-2-ene
2-methylpent-2-ene is an alkene with the following structure:
- It has a double bond between the second and third carbon atoms.
- The complete structure can be represented as:

CH3-CH2-C(CH3)=CH-CH3

### Step 2: Ozonolysis reaction
Ozonolysis involves the reaction of an alkene with ozone (O3), which leads to the formation of an ozonide intermediate. The double bond in the alkene is cleaved, and the ozonide is formed.

### Step 3: Formation of ozonide
For 2-methylpent-2-ene, the ozonide can be represented as follows:
- The ozonide will have the structure where the double bond is broken, and the ozonide is formed with the following structure:

CH3-CH2-C(O)-C(O)-CH3

### Step 4: Reduction of ozonide
The ozonide is then typically treated with a reducing agent, such as zinc (Zn) in water, which leads to the cleavage of the ozonide into carbonyl compounds.

### Step 5: Identify the products
Upon reduction, the ozonide will yield:
1. Propanal (CH3-CH2-CHO)
2. Acetone (CH3-C(=O)-CH3)

### Final Answer
Thus, the products formed from the ozonolysis of 2-methylpent-2-ene are propanal and acetone.
