Hint: International union of pure and applied chemistry (IUPAC) nomenclatural is a method of naming compounds on the basis of various alkyl, aryl functional groups, type of bonding, number of elements etc. IUPAC nomenclature is done to give specific names to a compound apart from its common name.
Complete step by step answer:
Firstly we should see which functional group is present in the compound and what substitutes are attached to the carbon atom.
As we see, in the above diagram the functional group is ketone$( - C - )$ one alkyl group is methyl group And one aryl group is Phenyl group is present.
This information will help us to determine the IUPAC name of the compound.
The alkyl aryl ketones are named as aryl alkanone according to the IUPAC rules. Therefore, we can name the compound as phenyl ethanone group, Phenyl is the aryl carbon chain is two carbons long (th) and suffix one comes from the functional group ketone.
So, the correct answer is “Option A”.
Additional Information:
The given compound is commonly known as acetophenone. But, the IUPAC name is phenyl ethanone,
Note:
Ketones are given names according to their alkane chain the -e from end is removed and suffix-one is added. The naming of Ketone is simply done by writing the names of substituent groups alphabetically and then adding ketone at the end.
