Answer:
Ketone, alcohol and unsaturation
Explanation:
The functional groups are the groups that identify the organic function of the molecule. For example, the hydroxyl (-OH) represents alcohol, the carbonyl (represented in the figure below) can represent a ketone or an aldehyde, and so each function has its representation.
The cortisone molecule is represented below, and each group is marked in blue. They are:
a, c, and d = carbonyl of ketone;
b = Â unsaturation (double bond) of alkene;
e, and f = hydroxyl of alcohol.
