Consider the given chemical reaction :

Reaction Mechanism: Oxidative Cleavage of Alkenes

This reagent combination acts as a strong oxidizing agent that completely cleaves the carbon-carbon double bond ($$\text{C}=\text{C}$$).

1. The $$\pi$$ and $$\sigma$$ bonds of the alkene double bond are broken entirely.
2. The two ring carbons originally involved in the double bond ($$\text{CH}=\text{CH}$$) are oxidized to carboxylic acid groups ($$-\text{COOH}$$).
