gentle fizz

Question 11

what is an ester

Answer 11

an ester is a molecule which contain the functional group ‘-C-O=C-O’ and can be identified by their distinctive fruity smell. They also evaporate easily (we say they are volatile) which makes them a useful group of compounds to use in perfumes and food flavourings.
