Question

Give the IUPAC name of ${C_6}{H_5}COC{H_3}$

Answer 1

Firstly by the basic rules of the IUPAC naming we get the rules followed for the correct naming process. Now these rules are, following priority order, the arrangement of the groups in the right alphabetical order for the sake of naming and to deduce the numbering by chief functional group. By following this we will get the right numbering and then we can put it in the correct sequence to get the right name.

Complete step by step answer:
In the given question we have to find out the correct IUPAC naming of the compound given in the problem statement.
Here we have to firsly take many of the things into the account:
The correct IUPAC naming is governed by various simle and useful rules which are given by the naming committee.
Some of them are :
While naming the priority order should be taken into account.
Apart from that we have to arrange the components in the alphabetical order when we have to write them in the IUPAC naming.
To start the numbering the beginning is with the carbon with the functional group with the highest priority in the priority order.
Whenever in case of cyclic if the ring has more carbons than the name after it.
In basic naming these rules are almost all we need to govern the naming process. This is not a branched compound although it has cyclic components of benzyl and the carbons in the functional chain are $8$ so the prefix would be phenyl.
Apart from that we can say that the functional group is the ketone so the suffix would be -one.
Now by that we will get the correct IUPAC name as 1-Phenylethanone.

Note:
Acetophenone is recovered as a by-product of the oxidation of ethylbenzene to ethylbenzene hydroperoxide. Ethylbenzene hydroperoxide is an intermediate in the commercial production of propylene oxide via the propylene oxide - styrene co-product process.
