Vedclass · Answer

(A) To determine the longest chain for $IUPAC$ nomenclature,we must include the principal functional group (ketone) and the double bond if possible. Starting from the right end to give the ketone the lowest possible locant,the numbering is as follows: $1$ (terminal $CH_3$),$2$ $(CH_2)$,$3$ $(C=O)$,$4$ $(CH_2)$,$5$ $(CH_2)$,$6$ $(C=)$,$7$ $(CH)$,$8$ $(CH_3)$. The longest carbon chain contains $8$ carbon atoms.

The number of carbon atoms in the longest chain during the $IUPAC$ nomenclature of the following compound is:
