Insects and other animals use pheromones as a way of communicating. The pheromone found in a bee sting is 3-methylbutyl ethanoate. Which organic products are formed when 3-methylbutyl ethanoate is heated under reflux with aqueous sodium hydroxide?

  • A$\text{CH}_3\text{CO}_2\text{H}$ and $(\text{CH}_3)_2\text{CHCH}_2\text{CH}_2\text{OH}$
  • B$\text{CH}_3\text{CO}_2\text{H}$ and $(\text{CH}_3)_2\text{CHCH}_2\text{CH}_2\text{O}^-\text{Na}^+$
  • C$\text{CH}_3\text{CO}_2^-\text{Na}^+$ and $(\text{CH}_3)_2\text{CHCH}_2\text{CH}_2\text{OH}$
  • D$\text{CH}_3\text{CO}_2^-\text{Na}^+$ and $(\text{CH}_3)_2\text{CHCH}_2\text{CH}_2\text{O}^-\text{Na}^+$
