The final product formed by the ozonolysis of compound `RCH=CR_2` is

Options

A. RCHO
B. `R_2CO`
C. Both (a) and (b)
D. None of these

Explanation

To determine the final product formed by the ozonolysis of the compound \( RCH=CR_2 \), we can follow these steps:

### Step 1: Understand Ozonolysis
Ozonolysis is a reaction where ozone (O₃) reacts with alkenes to cleave the double bond and form carbonyl compounds. The reaction typically involves the formation of an ozonide intermediate, which is then reduced (often using zinc, Zn) to yield the final products.

### Step 2: Identify the Structure of the Compound
The compound given is \( RCH=CR_2 \). This indicates that we have a double bond between a carbon atom attached to a substituent \( R \) and another carbon atom that has two substituents \( R \).

### Step 3: Reaction with Ozone
When \( RCH=CR_2 \) undergoes ozonolysis, the double bond will break. The ozone will add across the double bond, forming an ozonide intermediate.

### Step 4: Cleavage of the Ozonide
The ozonide will then be reduced, typically using zinc in an acidic medium. This reduction will lead to the formation of carbonyl compounds. Specifically, the products will be:
- An aldehyde from the carbon that was initially bonded to \( R \) (which is now \( RCHO \)).
- A ketone from the carbon that was bonded to two \( R \) groups (which is now \( R_2CO \)).

### Step 5: Identify the Final Products
Thus, the final products formed from the ozonolysis of \( RCH=CR_2 \) are:
- One molecule of aldehyde \( RCHO \)
- One molecule of ketone \( R_2CO \)

### Conclusion
The final products of the ozonolysis of the compound \( RCH=CR_2 \) are \( RCHO \) (aldehyde) and \( R_2CO \) (ketone).
