When a honeybee stings, it releases more than venom. It also releases a chemical that smells like bananas, a powerful alarm signal called isoamyl acetate. In this video we explore how bees use this scent to communicate danger, then recreate it in the lab through a Fischer esterification reaction. From reflux and distillation to testing it on real hives and confirming it with analytical chemistry, we show how a simple compound connects the hidden language of bees to classic organic chemistry. Want to recreate this experiment in your own lab? StonyLabs has you covered. They put together a custom kit with all the glassware I used; so you don’t have to hunt it down piece by piece. 👉 https://stonylab.com/products/isoamyl...
