The compound cetyl palmitate, $\text{C}_{15}\text{H}_{31}\text{CO}_2\text{C}_{16}\text{H}_{33}$, is a waxy solid. When cetyl palmitate is heated under reflux with an excess of aqueous sodium hydroxide, which products are produced?

  • A$\text{C}_{15}\text{H}_{31}\text{ONa}$ and $\text{C}_{16}\text{H}_{33}\text{CO}_2\text{Na}$
  • B$\text{C}_{15}\text{H}_{31}\text{CO}_2\text{Na}$ and $\text{C}_{16}\text{H}_{33}\text{ONa}$
  • C$\text{C}_{15}\text{H}_{31}\text{OH}$ and $\text{C}_{16}\text{H}_{33}\text{CO}_2\text{Na}$
  • D$\text{C}_{15}\text{H}_{31}\text{CO}_2\text{Na}$ and $\text{C}_{16}\text{H}_{33}\text{OH}$
