Vitamin A includes retinol. If the conditions are suitable, acidified $\text{KMnO}_4(aq)$ can be used to cleave $\text{C}=\text{C}$ bonds. Once these bonds have been cleaved, the resulting fragments may undergo additional oxidation. In what conditions is acidified $\text{KMnO}_4(aq)$ used, and what are the final oxidation products likely to contain?

  • Acold, dilute; aldehydes and carboxylic acids
  • Bcold, dilute; ketones and carboxylic acids
