In the normal method, ketones are named based on the names of the groups associated with the ketone group.
In the IUPAC method, ketones are named by adding ‘one’ to the end of the corresponding alkane name. Removes ‘e’ from the end of the English name and adds ‘one’.
After this, the IUPAC name of that ketone is obtained after writing the appropriate and lowest number of carbon atoms related to ketone group in series of carbon atoms with the help of IUPAC rules.
