A

(1) `3`-oxo-`2`-heptyne

B

(2) hept-`3`-yn-`4`-oxone

C

(3) hept-`4`-yn-`3`-one

Text Solution

Verified by Experts

The correct Answer is:
C
The principal function is . Thus, the compound should be named as an unsaturated ketone (alkynone). The numbering should be done so as to give the least possible number to the `C` atom of the group.
`overset(7)(CH_(3))overset(6)(CH_(2))underset("Hept-4-yn-2-one")(overset(5)(C) = overset(4)(C)underset(O)underset(||)overset(3)(C)overset(2)(CH_(2))overset(1)(CH_(3)))`
