Alkenes undergo a variety of oxidation reactions. With cold and neutral or alkaline `KMnO_(4)`, alkenes are oxidised to give vicinal diols. Oxidation with hot `KMnO_(4)` undergoes cleavage of C=C bond leading to the formation of carboxylic acids, ketones and carbon dioxide depending on the nature ofalkene. Reductive ozonolysis of alkenes give aldehydes or ketones.
2-Methyl propene on treatment with hot alkaline `KMnO_(4)` gives

Options

A. `(CH_(3))_(2)CO,HCOOH`
B. `(CH_(3))_(2)CO,CO_(2)`
C. `(CH_(3))_(2)CO,CH_(3)CHO`
D. `CH_(3)CHO,CH_(3)CH_(2)CHO`

Explanation

To solve the problem of what products are formed when 2-methylpropene is treated with hot alkaline KMnO4, we will follow these steps:

### Step 1: Identify the Structure of 2-Methylpropene
2-Methylpropene is an alkene with the following structure:
```
CH3
|
CH2=C
|
CH3
```
This structure indicates that there is a double bond between the second and third carbon atoms.

### Step 2: Understand the Reaction with Hot Alkaline KMnO4
When alkenes react with hot alkaline KMnO4, they undergo oxidative cleavage. This means that the double bond (C=C) will be broken, and the products will depend on the substituents attached to the double bond.

### Step 3: Perform the Oxidative Cleavage
For 2-methylpropene, the cleavage of the double bond will yield:
- One side of the double bond will lead to an aldehyde (specifically, formaldehyde, HCHO).
- The other side will lead to a ketone (specifically, acetone, CH3COCH3).

### Step 4: Further Oxidation of the Aldehyde
The formaldehyde (HCHO) produced can be further oxidized by the strong oxidizing agent (hot alkaline KMnO4) to form formic acid (HCOOH). Formic acid can then be further oxidized to carbon dioxide (CO2) and water (H2O).

### Step 5: Identify the Final Products
From the above steps, the products formed from the reaction of 2-methylpropene with hot alkaline KMnO4 are:
- Acetone (CH3COCH3)
- Carbon dioxide (CO2)

### Conclusion
Thus, the final answer is that the treatment of 2-methylpropene with hot alkaline KMnO4 gives acetone and carbon dioxide.
