Why does the smell of an ester become more prominent when it is poured into water?
Mr. Yahia Maharmeh says that Because the reactions are slow and reversible, you don't get a lot of ester produced in this time. The smell is often masked or distorted by the smell of the carboxylic acid. A simple way of detecting the smell of the ester is to pour the mixture into some water in a small beaker.Apart from the very small ones, esters are fairly insoluble in water and tend to form a thin layer on the surface. Excess acid and alcohol both dissolve and are tucked safely away under the ester layer.

The ester is also found in bees, where it is a pheromone released when the bee stings.

What molecule would you find ester bonds?
Ester bonds are found in molecules known as esters. Esters are formed by the reaction of a carboxylic acid with an alcohol, resulting in the loss of a water molecule. They have a distinct fruity smell and are commonly found in fruits, flowers, and various food flavors.
