Esters are organic compaounds containing the functional group of - COO - . The general formula is more complex. There are two sides to the - COO - .
The first end with an 'yl' (ex. methyl, ethyl) meaning C n H 2n+1. The other side of the - COO - ends with 'oate' (ex. propanoate, ehtanoate) and the general formula for that side is the same.
Examples of this are methyl methanoate and ethyl propanoate.
Esters are made by reacting alcohols with carboxylic acids.
For example, mixing methanol with ethanoic acid would make methyl ethanoate.
Esters are responsible for the smells of fruits and can therefore be extracted from fruits.
Their smell is also used for perfumes.
Esters can also be used for food flavouring.
Esters are volatile, meaning they have low boiling points and readily evapourate.
